The Double-Track Decision involved two policy "tracks". Initially, 1,000 of the 7,400 theater nuclear warheads would be removed from Europe, and the US would pursue bilateral negotiations with the Soviet Union, intended to limit theater nuclear forces. Should these negotiations fail, NATO would modernize its own LRTNF, or intermediate-range nuclear forces (INF), by replacing US

or "zero-zero" proposal.
It called for a hold on US deployment of GLCM and Pershing II systems, reciprocated by Soviet elimination of its SS-4, SS-5, and SS-20 missiles. There appeared to be little chance of the Zero Option being adopted due to Soviet opposition, but the gesture was well received by the European public. In February 1982, US negotiators put forth a draft treaty containing the Zero Option and a global prohibition on intermediate- and short-range missiles, with compliance ensured via a stringent, though unspecified, verification program.
Opinion within the Reagan administration on the Zero Option was mixed.

Caspar Weinberger, who supported a continued US nuclear presence in Europe, was skeptical of the plan, though eventually accepted it for its value in putting the Soviet Union "on the defensive in the European propaganda war". Reagan later recounted that the "zero option sprang out of the realities of nuclear politics in Western Europe".
The Soviet Union rejected the plan shortly after the US tabled it in February 1982, arguing that both the US and USSR should be able to retain intermediate-range missiles in Europe. Specifically, Soviet negotiators proposed that the number of INF missiles and aircraft deployed in Europe by each side be capped at 600 by 1985 and 300 by 1990. Concerned that this proposal would force the US to withdraw aircraft from Europe and not deploy INF missiles, given US cooperation with existing British and French deployments, the US proposed "equal rights and limits"—the US would be permitted to match Soviet SS-20 deployments.
Between 1981 and 1983, American and Soviet negotiators gathered for six rounds of talks, each two months in length—a system based on the earlier SALT talks. The US delegation was composed of Nitze,

There was little convergence between the two sides over these two years. A US effort to separate the question of nuclear-capable aircraft from that of intermediate-range missiles successfully focused attention on the latter, but little clear progress on the subject was made. In the summer of 1982, Nitze and Kvitsinsky took a "walk in the woods" in the

Nitze later said that his and Kvitsinsky's goal was to agree to certain concessions that would allow for a summit meeting between Brezhnev and Reagan later in 1982.
Nitze's offer to Kvitsinsky was that the US would forego deployment of the Pershing II and limit the deployment of GLCMs to 75. The Soviet Union, in return, would also have to limit itself to 75 intermediate-range missile launchers in Europe and 90 in Asia. Due to each GLCM launcher containing four GLCMs and each SS-20 launcher containing three warheads, such an agreement would have resulted in the US having 75 more intermediate-range warheads in Europe than the USSR, though Soviet SS-20s were seen as more advanced and maneuverable than American GLCMs. While Kvitsinsky was skeptical that the plan would be well-received in Moscow, Nitze was optimistic about its chances in Washington.
[ The deal ultimately found little traction in either capital. In the United States, the Office of the Secretary of Defense opposed Nitze's proposal, as it opposed any proposal that would allow the Soviet Union to deploy missiles to Europe while blocking American deployments. Nitze's proposal was relayed by Kvitsinsky to Moscow, where it was also rejected. The plan accordingly was never introduced into formal negotiations.]

meeting following the Nitze-Kvitsinsky walk, the proposal was received positively by the Joint Chiefs of Staff and Reagan. Following protests by Perle, working within the Office of the Secretary of Defense, Reagan informed Nitze that he would not back the plan. The State Department, then led by Haig, also indicated that it would not support Nitze's plan and preferred a return to the Zero Option proposal.[ Nitze argued that one positive consequence of the walk in the woods was that the Western European public, which had doubted American interest in arms control, became convinced that the US was participating in the INF negotiations in good faith.][
In early 1983, US negotiators indicated that they would support a plan beyond the Zero Option if the plan established equal rights and limits for the US and USSR, with such limits valid worldwide, and excluded British and French missile systems (as well as those of any other third party). As a temporary measure, the US negotiators also proposed a cap of 450 deployed INF warheads around the world for both the United States and Soviet Union. In response, Soviet negotiators proposed that a plan would have to block all US INF deployments in Europe, cover both missiles and aircraft, include third parties, and focus primarily on Europe for it to gain Soviet backing. In the fall of 1983, just ahead of the scheduled deployment of US Pershing IIs and GLCMs, the United States lowered its proposed limit on global INF deployments to 420 missiles, while the Soviet Union proposed "equal reductions": if the US cancelled the planned deployment of Pershing II and GLCM systems, the Soviet Union would reduce its own INF deployment by 572 warheads. In November 1983, after the first Pershing IIs arrived in West Germany, the Soviet Union ended negotiations.

In March 1986, negotiations between the US and the USSR resumed, covering not only the INF issue, but also the separate Strategic Arms Reduction Treaty (START I) and space issues (Nuclear and Space Talks). In late 1985, both sides were moving towards limiting INF systems in Europe and Asia. On 15 January 1986, Gorbachev announced a Soviet proposal for a ban on all nuclear weapons by 2000, which included INF missiles in Europe. This was dismissed by the United States as a public relations stunt and countered with a phased reduction of INF launchers in Europe and Asia with the target of none by 1989. There would be no constraints on British and French nuclear forces.

The treaty prohibited both parties from possessing, producing, or flight-testing ground-launched ballistic and cruise missiles with ranges of . Possessing or producing ground-based launchers of those missiles was also prohibited. The ban extended to weapons with both nuclear and conventional warheads, but did not cover air-delivered or sea-based missiles. Existing weapons had to be destroyed, and a protocol for mutual inspection was agreed upon. Each party had the right to withdraw from the treaty with six months' notice, "if it decides that extraordinary events related to the subject matter of this Treaty have jeopardized its supreme interests".

to be inheritors of the treaty obligations (the three Baltic states are considered to preexist their illegal annexation by the Soviet Union in 1940). The US did not focus immediate attention on the preservation of the INF Treaty because the disarmament of INF missiles already occurred. Eventually, the US began negotiations to maintain the treaty in the six newly independent states of the former Soviet Union that contained INF sites subject to inspection: Belarus, Kazakhstan, Russia, Turkmenistan, Ukraine, and Uzbekistan, with Russia being the USSR's official successor state and inheriting its nuclear arsenal. From these six countries, Belarus, Kazakhstan, Russia, and Ukraine entered agreements to continue the fulfillment of the INF Treaty. The remaining two states, Turkmenistan and Uzbekistan, became passive participants in the negotiations with approval from the other participating states due to the presence of a single inspection site in each country. Inspection of INF missile sites continued until May 31, 2001, as stipulated by the 13-year inspection agreement within the treaty. After this period, the United States and Russia continued to share national technical means of verification and notifications to ensure that each state maintained compliance. The treaty states continued to meet at Special Verification Committees after the end of the inspection period. There were 30 total meetings with the final meeting occurring in November 2016 in Geneva, Switzerland with the United States, Belarus, Kazakhstan, Russia, and Ukraine meeting to discuss compliance obligations.

has rarely acted to stop a number of presidential decisions regarding international treaties during the 20th and 21st centuries, there have been established a precedent that the president and executive branch can unilaterally withdraw from a treaty without congressional approval. On the day of the withdrawal, the US Department of Defense announced plans to test a new type of missile that would have violated the treaty, from an eastern NATO base. Military leaders stated the need for this new missile to stay ahead of both Russia and China, in response to Russia's continued violations of the treaty.
The US withdrawal was backed by most of its NATO allies, citing years of Russian non-compliance with the treaty. In response to the withdrawal, Russian Deputy Foreign Minister Sergei Ryabkov invited the US and NATO "to assess the possibility of declaring the same moratorium on deploying intermediate-range and shorter-range equipment as we have, the same moratorium Vladimir Putin declared, saying that Russia will refrain from deploying these systems when we acquire them unless the American equipment is deployed in certain regions." This moratorium request was rejected by NATO's Stoltenberg who said that it was not credible as Moscow had already deployed such warheads. On 5 August 2019, Putin stated, "As of August 2, 2019, the INF Treaty no longer exists. Our US colleagues sent it to the archives, making it a thing of the past."
On 18 August 2019, the US conducted a test firing of a missile that would not have been allowed under the treaty; a ground-based version of the Tomahawk

, who said that instead of crafting a plan to hold Russia accountable and pressure it into compliance, the Trump administration had offered Putin an easy way out of the treaty and played right into his hands. Similar arguments had been brought previously on 25 October 2018 by European members of NATO who urged the US "to try to bring Russia back into compliance with the treaty rather than quit it, seeking to avoid a split in the alliance that Moscow could exploit".[
NATO chief Stoltenberg suggested the INF Treaty could be expanded to include countries such as China and India, an idea that both the US and Russia had indicated being open to, although Russia had expressed skepticism that such an expansion could be achieved.
There were contrasting opinions on the withdrawal among American lawmakers. The INF Treaty Compliance Act (H.R. 1249) was introduced to stop the United States from using Government funds to develop missiles prohibited by the treaty, while Republican senators ]Jim Inhofe

issued statements of support for the withdrawal.
On 8 March 2019, the Foreign Ministry of Ukraine announced that since the United States and Russia had both pulled out of the treaty, it now had the right to develop intermediate-range missiles, citing Russian aggression against Ukraine as a serious threat to the European continent, and the presence of Russian Iskander-M nuclear-capable missile systems in Russian-annexed Crimea. Ukraine was home to about forty percent of the Soviet space industry, but was never allowed to develop a missile with the range to strike Moscow, only having both longer and shorter-ranged missiles, but it has the capability to develop intermediate-range missiles.
After the United States withdrew from the treaty, some American commentators wrote that this might allow the country to more effectively counter Russia and China's missile forces. This was later followed by the development and deployment of the Typhon Medium Range Capability weapon system in 2023.
According to Brazilian journalist Augusto Dall'Agnol, the INF Treaty's demise also needs to be understood in the broader context of the gradual erosion of the strategic arms control regime that started with the US withdrawal from the ABM Treaty in 2002 amidst Russia's objections.
