Work


Conventional deterrence

Mearsheimer's first book, ''Conventional Deterrence'' (1983), addresses the issue of how the decision to start a war depends on the projected outcome of the war, in other words, how the decision makers' beliefs about the outcome of the war affect the success or failure of deterrence. Mearsheimer's basic argument is that deterrence is likely to work when the potential attacker believes that an attack will be costly and is unlikely to succeed. However, if the potential attacker has reason to believe the attack will entail low costs and is likely to succeed, deterrence is likely to break down, which is now widely accepted to be how the principle of deterrence works. Specifically, Mearsheimer argues that the success of deterrence is determined by the strategy available to the potential attacker. He lays out three strategies. Firstly, an attrition strategy entails a high level of uncertainty about the outcome of war and high costs for the attacker. Secondly, a limited-aims strategy entails fewer risks and lower costs. Thirdly, a ''

'' strategy provides a way to defeat the enemy rapidly and decisively with relatively low costs. For Mearsheimer, failures in the modern battlefield are caused mostly by the potential attacker's belief that it can successfully implement a ''blitzkrieg'' strategy in which tanks and other mechanized forces are employed swiftly to cause deep penetration and to disrupt the enemy's rear. The two other strategies are unlikely to lead to deterrence failures because they entail a low probability of success, accompanied by high costs (

However, if the attacker has a coherent ''blitzkrieg'' strategy available, an attack is likely to ensue because its potential benefits outweigh the costs and risks of starting a war.

B. H. Liddell Hart

Mearsheimer's second book, ''Liddell Hart and the Weight of History'' (1988), reassesses the intellectual legacies of the 20th-century British military theorist
B. H. Liddell Hart Sir Basil Henry Liddell Hart (31 October 1895 – 29 January 1970), commonly known throughout most of his career as Captain B. H. Liddell Hart, was a British soldier, military historian and military theorist. He wrote a series of military histor ...
. While acknowledging that his own research had "profited greatly from his stimulating writings" and that Liddell Hart's works should still be considered "essential reading for serious students of strategy and warfare" (p. x), Mearsheimer argues that much of the conventional wisdom on Liddell Hart's contributions to modern military thought was flawed. In particular, the theory of the
indirect approach The Indirect approach is a military strategy described and chronicled by B. H. Liddell Hart after World War I. It was an attempt to find a solution to the problem of high casualty rates in conflict zones with high force to space ratios, such as the ...
, which Liddell Hart developed in the 1930s, is so vague and tautological that "virtually every military victory can be ascribed to t" (p. 87). Moreover, Liddell Hart's limited attempts to operationalize the theory clearly indicated that what he primarily had in mind was to "indirectly" defeat a continental adversary by "break ngthe morale of the enemy's civilian population, not to destroy his military forces, which of course is what the blitzkrieg is concerned with" (p. 88). The common practice of tracing the intellectual origins of the
blitzkrieg Blitzkrieg ( , ; from 'lightning' + 'war') is a word used to describe a surprise attack using a rapid, overwhelming force concentration that may consist of armored and motorized or mechanized infantry formations, together with close air ...
strategy to the indirect approach is thus mistaken since there was "no evidence... that Liddell Hart understood the importance of the deep strategic penetration hat distinguishes ''blitzkrieg''''before''
World War II World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great power ...
" (p. 43). Not surprisingly, Liddell Hart was proven utterly wrong on the fundamental military questions of the
interwar period In the history of the 20th century, the interwar period lasted from 11 November 1918 to 1 September 1939 (20 years, 9 months, 21 days), the end of the First World War to the beginning of the Second World War. The interwar period was relative ...

Heinz Guderian Heinz Wilhelm Guderian (; 17 June 1888 – 14 May 1954) was a German general during World War II who, after the war, became a successful memoirist. An early pioneer and advocate of the "blitzkrieg" approach, he played a central role in th ...
allowed Liddell Hart to exaggerate his influence on ''blitzkrieg'' in their memoirs in exchange for helping them promote an image of themselves as having been military innovators first and foremost rather than

henchmen. In the case of Guderian, Liddell Hart effectively acted as his "literary agent" for the English-speaking world (p. 185). Fritz Bayerlein, who served as General

's chief of staff in the North African campaign, similarly helped Liddell Hart manipulate the historical record for a false portrayal of Rommel as having been his "pupil" (pp. 193–201). Mearsheimer concludes by emphasizing the importance of a robust intellectual community that can hold "defense intellectuals" accountable:
Defense intellectuals need to know that informed judgments will be passed on their views and their overall conduct and that charlatanism will be exposed. Absence of penalties for misbehavior means no brake on the spread of false ideas. Liddell Hart actually was held accountable at one point. The significant ebbing of his influence during and immediately after World War II was, in effect, punishment for offering flawed ideas for how to deal with the
Third Reich Nazi Germany (lit. "National Socialist State"), ' (lit. "Nazi State") for short; also ' (lit. "National Socialist Germany") (officially known as the German Reich from 1933 until 1943, and the Greater German Reich from 1943 to 1945) was ...
. What is disturbing about Liddell Hart's case, however, is that eventually he was able to escape from this predicament by rewriting history. The national security community, especially its historians, need to be alert to historical manipulation for selfish reasons (p. 224).
Mearsheimer's arguments about Liddell Hart generated varied responses. For example, the founder of the
Israel Defense Forces The Israel Defense Forces (IDF; he, צְבָא הַהֲגָנָה לְיִשְׂרָאֵל , ), alternatively referred to by the Hebrew-language acronym (), is the national military of the Israel, State of Israel. It consists of three servic ...
Operational Theory Research Institute, Simon Naveh, concurred in a separate study, which found that "by distorting the actual historical circumstances of the ''Blitzkrieg'' formation iddell Hartobscured its temporal and cognitive origins.... The early-1950s display of the transformed version of ''Blitzkrieg'' as a historical fact, carrying the joint signature of Liddell Hart and Guderian, lent it an authentic touch and a professional legitimacy that could not be shaken." In contrast, Richard Swain of the US Army Command and General Staff College argued that while "there is a good deal about which Mearsheimer is correct," he likely overstates the extent to which Liddell Hart's historical distortions were consciously self-serving: "To charge Liddell Hart with cleverly creating a deception requires one first to accept that Liddell Hart knew he had been wrong. There is little or no evidence of that."


Nuclear proliferation and deterrence

In 1990, Mearsheimer published an essay in which he predicted that Europe would revert to a multipolar environment, similar to that of the first half of the 20th century, if American and Soviet forces left after the end of the

International institutions

In a widely cited 1994 article, "The False Promise of International Institutions," Mearsheimer tackles popular arguments about the ability of institutions to discourage war and promote peace among states. He recognizes that states often find institutions to be useful, but the imperative of relentless security competition under anarchy means that state behavior is primarily a function of the distribution of power in the international system. Institutions, at best, are "merely an intervening variable in the process" (p. 13). Mearsheimer maintains that "institutionalist theories" offered poor alternatives to this grim picture of international politics. In particular, influential neoliberal institutionalist arguments ignore relative-gains concerns as a barrier to cooperation and fail to provide evidence that instances of cooperation, which are commonly attributed to institutions, would not have taken place in their absence. Other theories such as collective security theory and
critical theory A critical theory is any approach to social philosophy that focuses on society and culture to reveal, critique and challenge power structures. With roots in sociology and literary criticism, it argues that social problems stem more from s ...
likewise fell short on logical and empirical grounds. In a response article, the prominent neoliberal institutionalist scholars

and Lisa Martin acknowledge that seminal institutionalist works tended to neglect the problem of relative gains but maintain that the debate spawned by realist challenges "has made distributional and bargaining issues more salient than they were in early neoliberal thinking" (p. 45). Mearsheimer charges that "a careful look at Keohane and Martin's response reveals that liberal institutionalism in its latest form is no longer a clear alternative to realism, but has, in fact, been swallowed up by it."


Offensive realism

Mearsheimer is the leading proponent of offensive realism. The structural theory, unlike the

, offensive realism maintains that states are not satisfied with a given amount of power but seek hegemony for security because the anarchic makeup of the international system creates strong incentives for states to seek opportunities to gain power at the expense of competitors. Mearsheimer summarized that view in his 2001 book ''The Tragedy of Great Power Politics'':
Given the difficulty of determining how much power is enough for today and tomorrow, great powers recognize that the best way to ensure their security is to achieve hegemony now, thus eliminating any possibility of a challenge by another great power. Only a misguided state would pass up an opportunity to be the hegemon in the system because it thought it already had sufficient power to survive.

. Furthermore, he argues that regional hegemons attempt to prevent other states from gaining hegemony in their region since peer competitors would be free to roam and thus could interfere in the established regional hegemon's neighborhood. States that have achieved regional hegemony, such as the United States, will act as offshore balancers by interfering in other regions if the great powers in those regions cannot prevent the rise of a hegemon.

In a 2004 speech, Mearsheimer praised the British historian
E. H. Carr Edward Hallett Carr (28 June 1892 – 3 November 1982) was a British historian, diplomat, journalist and international relations theorist, and an opponent of empiricism within historiography. Carr was best known for '' A History of Soviet R ...

'' and argued that Carr was correct when he claimed that international relations were a struggle of all against all, with states always placing their own interests first. Mearsheimer maintained that Carr's points were still as relevant for 2004 as for 1939 and went on to deplore what he claimed was the dominance of "

Night watchman

Night watchman in Mearsheimer's terminology is a "global hegemon", a theoretical impossibility according to '' The Tragedy of Great Power Politics''. Nevertheless, in 1990, Mearsheimer mentioned the existence of a "watchman". Democracies lived at peace because "America's hegemonic position in NATO ... mitigated the effects of anarchy on the Western democracies and induced cooperation among them ... With the United States serving as a ''night watchman'' (emphasis added), fears about relative gains among the Western European states were mitigated ..." Afterwards, Mearsheimer did not mention the "watchman" for some time. A decade later, he described the "international anarchy" as having not changed with the end of the Cold War, "... and there are few signs that such change is likely any time soon. States remain the principal actors in world politics and there is still no ''night watchman'' standing above them." Five more years later, Mearsheimer confirmed that "in an anarchic system there is no ''night watchman'' for state to call when trouble comes knocking at their door." Precisely two decades after Mearsheimer had detected the watchman in the world for the last time, he rediscovered the watchman, which exists and keeps Europe at peace. The article "Why Is Europe Peaceful Today?" unambiguously answers, "The reason is simple: the United States is by far the most powerful country in the world and it effectively acts as a ''night watchman''."


Gulf War

In January and early February 1991, Mearsheimer published two op-eds in the ''Chicago Tribune'' and ''The New York Times'' and argued that the war to liberate
Kuwait Kuwait (; ar, الكويت ', or ), officially the State of Kuwait ( ar, دولة الكويت '), is a country in Western Asia. It is situated in the northern edge of Eastern Arabia at the tip of the Persian Gulf, bordering Iraq to Iraq–Ku ...
from Iraqi forces would be quick and lead to a decisive US victory, with less than 1,000 American casualties. Mearsheimer's argument was based on several points. Firstly, the Iraqi Army was a

military that was unprepared to fight mobile armored battles. Secondly, US armored forces were better equipped and trained. Thirdly, US artillery was also far better than its Iraqi counterpart. Fourthly, US airpower, unfettered by the weak Iraqi air force, should prove devastating against Iraqi ground forces. Fifthly and finally, the forward deployment of Iraqi reserves boded ill for their ability to counter US efforts to penetrate the Iraqi defense line along the Saudi–Kuwaiti border. All of those predictions came true during the course of the war.


Noelle-Neumann controversy

In October 1991, Mearsheimer was drawn into a bitter controversy at the University of Chicago regarding
Elisabeth Noelle-Neumann Elisabeth Noelle-Neumann (19 December 1916 – 25 March 2010) was a German political scientist. Her most famous contribution is the model of the spiral of silence, detailed in ''The Spiral of Silence: Public Opinion – Our Social Skin''. The m ...
, then a visiting professor from Germany. Noelle-Neumann was a prominent German pollster and a leading academic on public opinion research, who authored the highly regarded book, '' The Spiral of Silence.'' The debate centered on an article written for '' Commentary'' magazine by Leo Bogart, "The Pollster and the Nazis," which described Noelle-Neumann's past employment as a writer and editor for the Nazi newspaper '' Das Reich'' from 1940 to 1942. Noelle-Neumann's response to the article was to claim that "texts written under a dictatorship more than 50 years ago cannot be read as they were in 1937, 1939 or 1941. Severed from the time and place where they were written, they are no longer real, for reality is in part based on time and place." As chairman of Chicago's political science department at the time, Mearsheimer sat down with Noelle-Neumann to discuss the article and the allegations. After meeting with her for over three hours, Mearsheimer publicly declared, "I believe that Noelle-Neumann was an anti-Semite," and he spearheaded a campaign to ask her for an apology. He joined other University of Chicago faculty in writing a joint piece for Commentary Magazine that reacted to Noelle-Neumann's reply to the accusation against her. They declared that "by providing rhetorical support for the exclusion of Jews, her words helped make the disreputable reputable, the indecent decent, the uncivilized civilized, and the unthinkable thinkable." Mearsheimer said, "Knowing what we know now about the Holocaust, there is no reason for her not to apologize. To ask somebody who played a contributing role in the greatest crime of the 20th century to say 'I'm sorry' is not unreasonable."


''The Israel Lobby and U.S. Foreign Policy''

Statements on Israeli wars and Palestinian statehood

Mearsheimer was critical of the
2006 Lebanon War The 2006 Lebanon War, also called the 2006 Israel–Hezbollah War and known in Lebanon as the July War ( ar, حرب تموز, ''Ḥarb Tammūz'') and in Israel as the Second Lebanon War ( he, מלחמת לבנון השנייה, ''Milhemet Leva ...

He said that the Israel lobby played a key role in enabling Israel's counterproductive response by preventing the US from exercising independent influence. Mearsheimer was also critical of Israel's offensive against Hamas in the Gaza Strip that began in December 2008. He argued that it would not eliminate

's capability to fire missiles and rockets at Israel and that it would not cause Hamas to end its fight with Israel. In fact, he argued that relations between Israel and the Palestinians were likely to get worse in the years ahead. Mearsheimer emphasizes that the only hope for Israel to end its conflict with the Palestinians is to end the occupation and to allow the Palestinians to have their own state in Gaza and the West Bank. Otherwise, Israel will turn itself into an "apartheid state". That would be a disastrous outcome for Israel but also the United States and especially the Palestinians. Mearsheimer's criticisms of Israel further extended to its possession of nuclear weapons. In remarks made at the

in 2010, Mearsheimer asserted that a nuclear Israel was contrary to US interests and questioned Israel's accountability in the matter. He stated that there was "no accountability for Israel on any issue" because he surmised, "The Israelis can do almost anything and get away with it."


"Future of Palestine" lecture

In April 2010, Mearsheimer delivered the Hisham B. Sharabi Memorial Lecture at the Palestine Center in Washington, DC, which he titled "The Future of Palestine: Righteous Jews vs. the New Afrikaners." He argued that "the

state. According to Mearsheimer, such a state would not be politically viable, most American Jews would not support it, and it would eventually become a democratic binational state politically dominated by its Palestinian majority. He suggested that "American Jews who care deeply about Israel" could be divided into three categories: the "new

", who will support Israel even if it is an apartheid state; "righteous Jews", who believe that individual rights are universal and apply equally to Jews and Palestinians; and the largest group, which he called the "great ambivalent middle". He concluded that most of the "great ambivalent middle" would not defend an apartheid Israel because "American Jews are among the staunchest defenders of traditional liberal values." Accordingly, the "new Afrikaners" would become increasingly marginalized over time. Mearsheimer stated that he "would classify most of the individuals who head the Israel lobby's major organizations as "'new Afrikaners'" and specifically listed a number of prominent Jews and Jewish organizations, including

Allegations of antisemitism

In 2011, John Mearsheimer wrote a back-cover blurb for controversial author Gilad Atzmon's book ''The Wandering Who? A Study of Jewish Identity Politics'': "Gilad Atzmon has written a fascinating and provocative book on Jewish identity in the modern world. He shows how assimilation and liberalism are making it increasingly difficult for Jews in the Diaspora to maintain a powerful sense of their 'Jewishness.' Panicked Jewish leaders, he argues, have turned to Zionism (blind loyalty to Israel) and scaremongering (the threat of another Holocaust) to keep the tribe united and distinct from the surrounding goyim. As Atzmon's own case demonstrates, this strategy is not working and is causing many Jews great anguish. ''The Wandering Who?'' should be widely read by Jews and non-Jews alike." (posted on Foreign policy) Mearsheimer's endorsement of Atzmon's book was met with accusations of antisemitism by prominent Jewish writers and intellectuals.

wrote an article in response, "Why are John Mearsheimer and Richard Falk Endorsing a Blatantly Anti-Semitic Book?" It stated that the book "argues that Jews seek to control the world." Mearsheimer denied the charges of antisemitism in that he had "no reason to amend it or embellish" his blurb and defended his position. Writing in regard to the charge by Goldberg that Atzmon is anti-Semitic and, by implication, so is his positive review of Atzmon's book, Mearsheimer responded: "Atzmon's basic point is that Jews often talk in universalistic terms, but many of them think and act in particularistic terms. One might say they talk like liberals but act like nationalists.... It is in this context that he discusses what he calls the 'Holocaust religion,' Zionism, and Israel's treatment of the Palestinians. Again, to be perfectly clear, he has no animus toward Judaism as a religion or with individuals who are Jewish by birth."


Rise and containment of China

Mearsheimer asserts that

. The American motivation for doing so will be to gain a position of overwhelming security and superiority against its neighbors, which the US sees as potential challengers to its status. Additionally, he maintains that the US will attempt to form a balancing coalition that consists primarily of India, Japan, the Philippines, South Korea, Vietnam, and Indonesia to counter the growing strength and power projection capabilities of China. Mearsheimer presented a fuller statement of his views on China's rise in his 2014 updated edition of '' The Tragedy of Great Power Politics'', arguing that "if China continues its striking economic growth over the next few decades, it is likely to act in accordance with the logic of offensive realism.... Specifically, it will try to dominate Asia the way the United States dominates the Western Hemisphere." In accordance with the theory's structural logic, China will pursue regional hegemony not because its domestic politics or ideology inclines it toward aggression but because "domination offers the best way to survive under international anarchy" (p. 368). Mearsheimer stressed that China was simply following America's example in that regard:
These ambitious goals make good strategic sense for China (although this is not to say China will necessarily be able to achieve them). Beijing should want a militarily weak and isolated India, Japan, and Russia as its neighbors, just as the United States prefers a militarily weak Canada and Mexico on its borders. What state in its right mind would want other powerful countries located in its region? All Chinese surely remember what happened over the last century when Japan was powerful and China was weak.... hey alsosurely remember what happened in the hundred years between the

Why should we expect China to act differently than the United States? Are the Chinese more principled than we are? More ethical? Are they less nationalistic? Less concerned about their survival? They are none of these things, of course, which is why China is likely to follow basic realist logic and attempt to become a regional hegemon in Asia (pp. 374-375).

'' magazine, Mearsheimer clarified, "It is unlikely that China will go on a rampage and conquer other Asian countries. Instead, China will want to dictate the boundaries of acceptable behavior to neighboring countries, much the way the United States does in the Americas. An increasingly powerful China is also likely to try to push the United States out of Asia, much the way the United States pushed the European great powers out of the Western Hemisphere." In his response, Brzezinski argued, "How great powers behave is not predetermined.... For its part, the Chinese leadership appears much more flexible and sophisticated than many previous aspirants to great power status." Mearsheimer responded that Chinese leaders are indeed prudent and have no incentive to "pick a fight" with the United States at the moment, but "what we are talking about is the situation in 2025 or 2030, when China has the military muscle to take on the United States. What happens then, when China has a much larger gross national product and a much more formidable military than it has today? The history of great powers offers a straightforward answer In a widely debated 2021 ''Foreign Affairs'' article, Mearsheimer observed that the United States was destined to compete aggressively with China as long as the latter continued to grow into a militarily and economically powerful state in East Asia. However, contrary to realist logic, the United States in the post-Cold War period had "promoted investment in China and welcomed the country into the global trading system, thinking it would become a peace-loving democracy and a responsible stakeholder in a U.S.-led international order" (p. 48). In effect, by pursuing a policy of engagement, the U.S. had facilitated China's dangerous rise to great-power status and hastened the onset of a

:
Nobody can say that engagement wasn't given ample opportunity to work, nor can anyone argue that China emerged as a threat because the United States was not accommodating enough....China's economy experienced unprecedented growth, but the country did not turn into a liberal democracy or a responsible stakeholder. To the contrary, Chinese leaders view liberal values as a threat to their country's stability, and as rulers of rising powers normally do, they are pursuing an increasingly aggressive foreign policy. There is no way around it: engagement was a colossal strategic mistake (pp. 54-55).

''Why Leaders Lie''

Mearsheimer wrote a book, ''Why Leaders Lie'' (Oxford University Press, 2011), which analyzes lying in international politics. He argues that leaders lie to foreign audiences because they think that it is good for their country. For example, he maintains that US President Franklin D. Roosevelt lied about the ''Greer'' incident in September 1941 because he was deeply committed to getting America into
World War II World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great power ...

but that George W. Bush and some of his key advisors lied to the American people about the threat from Iraq. Mearsheimer argues that leaders are most likely to lie to their own people in democracies that fight wars of choice in distant places. He says that it is difficult for leaders to lie to other countries because there is not much trust among them, especially when security issues are at stake, and trust is needed for lying to be effective. Mearsheimer states that it is easier for leaders to lie to their own people because there is usually a good deal of trust between them. Mearsheimer does not consider the moral dimension of international lying, which he views from a utilitarian perspective. He argues that there are five types of international lies. # ''Inter-state lies'' occur if the leader of one country lies to a leader of another country or, more generally, any foreign audience, to induce a desired reaction. # ''Fear-mongering'' occurs if a leader lies to his or her own domestic public. # ''Strategic cover-ups'' are lies to prevent controversial policies and deals from being made known publicly. # ''Nationalist myths'' are stories about a country's past that portray that country in a positive light and its adversaries in a negative light. # ''Liberal lies'' are given to clear up the negative reputation of institutions, individuals, or actions. He explains the reasons for leaders pursuing each of the different kinds of lies. His central thesis is that leaders lie more frequently to domestic audiences than to leaders of other states. That is because international lying can have negative effects, including "blowback" and "backfiring". Blowback occurs if telling international lies helps cause a culture of deceit at home. Backfiring occurs if telling a lie leads to a failed policy. He also emphasizes that there are two other kinds of deception besides lying: "concealment", a leader remaining silent about an important matter, and "spinning", a leader telling a story that emphasizes the positive and downplays or ignores the negative.


Liberal international order

In ''The Great Delusion: Liberal Dreams and International Realities'' (Yale University Press, 2018) Mearsheimer presents a critique of the geopolitical strategy he refers to as "liberal hegemony". His definition of liberal hegemony includes a three-part designation of it as an extension of

, who trace the origins of the liberal international order to the early Cold War, he asserted that the Cold War liberal order had in fact been a "bounded order", designed to help the United States and its allies compete more effectively against the communist bloc. Although the US-led order became truly international after the collapse of the Soviet Union, the policies that undergird the order tended to precipitate its demise to the point that " en if Western policymakers had been wiser stewards of that order, they could not have extended its longevity in any meaningful way" (p. 30). In particular, US-led efforts to expand the order's membership by spreading democracy were bound to backfire by provoking nationalist resistance, embroiling the US in disastrous military adventures, and stoking hostility among rival powers such as Russia and China. Liberal internationalist policies also tended to collide with nationalism and economic concerns within the liberal countries themselves, as illustrated by key events such as

to the US presidency. Finally, the drive to integrate rising powers such as China into the liberal international order effectively "helped China become a great power, thus undercutting unipolarity, which is essential for maintaining a liberal world order" (p. 42). Mearsheimer concluded by predicting that the liberal international order would be replaced by three distinct "realist orders" in the near term: "a thin international order", primarily concerned with arms control and managing the global economy, and two bounded orders, led respectively by China and the United States (p. 44). His claims about the liberal international order have sparked a lively debate and prompted responses from scholars such as

, Christopher Layne, Jennifer Pitts, Jack Snyder, William C. Wohlforth, and C. William Walldorf. In a critique of ''The Great Delusion'', Wohlforth writes that the book fails to make good on its core claim: "First, you cannot establish a causal connection between liberalism and imprudent foreign policy by looking at only liberalism and imprudent foreign policy. Because Mearsheimer subjects no other ideology to the same scrutiny to which he subjects liberalism, there is no way to know whether liberalism stands out this regard.... Second, you cannot establish that a permissive systemic environment is a necessary condition by looking only at cases that occur in a permissive strategic environment." Wohlforth also argues that ''The Great Delusion'' is inconsistent with Mearsheimer's ''Tragedy of Great Power Politics'': "Given that other great powers were destined to come back, and the theory’s stipulation that their preferences (i.e., revisionism) are independent of anything the U.S. does (because nothing the U.S. does can reduce their uncertainty about U.S. intentions, and vice-versa), why would a unipolar U.S. not seek to expand and lock in gains when it had the opportunity to do so?" Mearsheimer makes important reference to Laurence Lampert's nihilistic Strauss interpretation in his book "The Great Delusion".


Ukraine


Nuclear weapons and Ukraine

After the end of the Soviet Union, the newly independent Ukraine had a large arsenal of nuclear weapons on its territory. However, in 1994, Ukraine agreed to give up nuclear arms and become a member of the Nuclear Nonproliferation Treaty; within two years, it had removed all atomic weapons. Almost alone among observers, Mearsheimer was opposed to that decision because he saw that Ukraine without a nuclear deterrent would likely be subjected to aggression by Russia. As early as 1993, he suggested that Ukraine should retain its nuclear weapons as a deterrent.


2014 Crimean crisis

Mearsheimer had warned in 1993 that a nuclear-free Ukraine would remain exposed to the danger of Russian attempts at reconquest. In 2014, he retrospectively criticized the geopolitical reorientation of the United States under

'' in August 2014, he assigned the main blame for the outbreak of the conflict to the United States and its Western allies.
Since the mid-1990s, Russian leaders have adamantly opposed NATO enlargement, and in recent years, they have made it clear that they would not stand by while their strategically important neighbor turned into a Western bastion. For Putin, the illegal overthrow of Ukraine’s democratically elected and pro-Russian president -- which he rightly labeled a “coup” -- was the final straw. He responded by taking Crimea, a peninsula he feared would host a NATO naval base, and working to destabilize Ukraine until it abandoned its efforts to join the West.
The narrative that Russia had only been waiting for opportunities to annex Ukraine is seen as erroneous by Mearsheimer. The U.S. and European political elites had been caught unprepared by the events "because they attach little importance to the logic of realism in the 21st century and assume that European unity and freedom can be guaranteed by means of liberal principles such as the rule of law, economic interdependence, and democracy." The U.S., aware of Russia's rejectionist stance, which is understandable because of Russia's security interests, would have pushed for the eastward expansion of the EU and NATO and supported the democratization of Ukraine. Mearsheimer considers Putin's reaction understandable because Ukraine (as a non-aligned state) is "indispensable" as a buffer for Russia's security needs. Mearsheimer compared NATO expansion into Eastern Europe, led by NATO, and the planned inclusion of Ukraine to the hypothetical scenario of a Chinese military alliance in North America: "Imagine the American outrage if China built an impressive military alliance and tried to include Canada and Mexico." Mearsheimer argued in a piece for ''Foreign Affairs'' that Russia's annexation of the Crimea was fueled by concerns that it would lose access to its

to publish their response in the November/December 2014 issue of ''Foreign Affairs''. Mearsheimer sees NATO's eastward expansion as a dangerous provocation of Russia. He invokes George F. Kennan as one of the first critical admonishers who warned in 1998 of the danger of war as a result of eastward enlargement. Mearsheimer attributes the political mistakes to the lack of political realism or the great influence of the "liberal hegemony" school of thought in both the Democratic Party and the Republican Party. The only sensible way out of the crisis, he said, is to soberly factor in Russia's security interests, like those of any other power. Ukraine, he said, must accept the role of buffer or bridge given to it by its geostrategic situation. Anything else, he said, was abstract and meaningless in terms of

2022 Russian invasion of Ukraine

In his 25 September 2015 lecture "Why is Ukraine the West's Fault?." Mearsheimer stated that the West (the US and the EU) was leading Ukraine down the primrose path, that the Western powers were encouraging Ukraine to become part of the West (even though they would be rebuffed), that they were encouraging the Ukraine government to pursue a hardline policy towards Russia, and that "the end result is that Ukraine is going to get wrecked". In the same lecture Mearsheimer declared: "If you really want to wreck Russia, what you should do is to encourage it to try to conquer Ukraine. Putin is much too smart to try that". Following the

, Mearsheimer reiterated that NATO and the EU were largely to blame for the war in Ukraine. In an interview with ''The New Yorker'', Mearsheimer stated: "I think all the trouble in this case really started in April 2008, at the NATO Summit in Bucharest, where afterward NATO issued a statement that said Ukraine and Georgia would become part of NATO. The Russians made it unequivocally clear at the time that they viewed this as an existential threat, and they drew a line in the sand. Nevertheless, what has happened with the passage of time is that we have moved forward to include Ukraine in the West to make Ukraine a Western bulwark on Russia’s border... NATO expansion is the heart of the strategy, but it includes E.U. expansion as well, and it includes turning Ukraine into a pro-American liberal democracy, and, from a Russian perspective, this is an existential threat." Mearsheimer says Ukraine's political leeway is determined by how it manages to strike a balance between Western orientation and consideration for Russian security interests. Mearsheimer does not deny Russia's aggression in this regard, but his criticism is directed at EU and NATO. "Given the West’s talk about eventual NATO membership and association agreements with the EU, how were politicians in Ukraine to resist the appeal of eventual inclusion? But if they succumb to that temptation they put themselves at risk of Russia’s wrath." In a subsequent interview in November 2022 to the same journalist of ''The New Yorker'', Mearsheimer argued that since the beginning of the conflict Russia has not been interested in the occupation of Ukraine, but only in the annexation of its south-eastern territories (the ''

). The main proof of this would be the fact that if Putin had really intended to occupy the entire territory of Ukraine, he would not have used an army consisting of only 190,000 soldiers. The bombings on Kyiv had and have the sole purpose of inducing the Ukrainian government and its western allies to accept the recognition of the annexation to Russia of the four aforementioned territories. In an interview with CSPAN in late March 2022, Mearsheimer has stated that he considers American involvement with the

to be secondary in terms of geopolitical priorities to immediate concerns which he associates with the containment of threats to geopolitical stability being caused by contemporary Chinese geopolitics, which Mearsheimer considers as a more immediate threat to geopolitical concerns in the United States. Mearsheimer debated the Russian invasion with Polish MP Radoslaw Sikorski in May 2022. Sikorski has taken a position on the Russian invasion of Ukraine identifying Putin as a culprit in conducting the invasion of Ukraine against the position of Mearsheimer that Putin is pursuing a realist geopolitical plan to secure Russian national interests in the presence of perceived threats from an expanding

Hypothesis testing in international relations

In 2013, Mearsheimer and Walt published "Leaving theory behind: Why simplistic hypothesis testing is bad for International Relations." They point out that in recent years, scholars of international relations have devoted less effort to creating and refining theories or using them to guide empirical research. Instead is a focus on what they call a simplistic hypothesis testing, which emphasizes discovering well-verified empirical regularities. They state that to be a mistake because insufficient attention to theory leads to misspecified empirical models or misleading measures of key concepts. They also point out that because of the poor quality data in international relations, it is less likely that the efforts will produce cumulative knowledge. It will lead to only a short-term gain and will make scholarship less useful to concerned citizens and policymakers. Theories give a scholar an overarching framework of the myriad realms of activity. Theories are like maps and aim to simplify a complex reality, but unlike maps, theories provide a causal story by saying that one or more factors can explain a particular phenomenon. Theories attempt to simplify assumptions about the most relevant factors in the aim to explain how the world works. Some grand theories like realism or liberalism claim to explain broad patterns of state behavior, and middle-range theories focus on more narrowly defined phenomena like coercion, deterrence, and economic sanctions. They list eight reasons why theories are important. The problems that arise from inadequate attention to theory is that it impossible to construct good models or interpret statistical findings correctly. By privileging hypothesis testing, that is overlooked. It might make sense to pay more attention to hypothesis testing if it produced much useful knowledge about international relations, but Mearsheimer and Walt claim that it is not the case and that the simplistic hypothesis test is inherently flawed. One of the consequences omitted variable bias, which is often treated as a methodological issue, but it should be treated as a theoretical matter. Selection bias is also a problem that arise from inadequate attention to theory. To examine that more clearly, the authors point out James Fearson's critique of Paul Huth and Bruce Russett's analyses of extended deterrence. Mearsheimer and Walt also point out that contemporary international relations scholarship faces challenging measurement issues because of inadequate attention to theory and cause misleading measures. A few examples are given to support their claim, including Dan Reiter and Allan Stam's ''Democracies at War''. Mearsheimer and Walt state that it is a sophisticated study but contains questionable measures of key concepts and that the measure to test their idea do not capture the theories core concepts. Poor data, the absence of explanation, and the lack of cumulation are other problems that arise from inadequate attention to theory by focusing too much on simplistic hypothesis testing.

In 2019, Mearsheimer said his preferred candidate in the 2020 Democratic presidential primary was
