A preemptive war is a
war that is commenced in an attempt to repel or defeat a perceived imminent offensive or invasion, or to gain a strategic advantage in an impending (allegedly unavoidable) war ''shortly before'' that attack materializes. It is a war that preemptively 'breaks the peace' before an impending attack occurs.
Preemptive war is sometimes confused with
preventive war
A preventive war is an armed conflict "initiated in the belief that military conflict, while not imminent, is inevitable, and that to delay would involve greater risk." The party which is being attacked has a latent threat capability or it has sh ...
: the difference is that a preventive war is launched to destroy the potential threat of the targeted party, when an attack by that party is not
imminent or known to be planned. The U.S. Department of Defense defines a preventive war as an armed conflict "initiated in the belief that military conflict, while not imminent, is inevitable, and that to delay would involve greater risk." A preemptive war is launched in anticipation of immediate aggression by another party. Most contemporary scholarship equates preventive war with aggression, and therefore argues that it is illegitimate.

Thus, Germany was left with no option but to preemptive invade Poland to halt the alleged Polish plans to invade Germany. It was later discovered that Germany had fabricated the evidence for the alleged Polish saboteurs as a part of the
Gleiwitz incident.
World War II (1939–1945)

The scholar
Abraham David Sofaer identified four key elements for justification of preemption:
# The nature and magnitude of the threat involved;
# The likelihood that the threat will be realized unless preemptive action is taken;
# The availability and exhaustion of alternatives to using force;
# Whether using preemptive force is consistent with the terms and purposes of the UN Charter and other applicable international agreements.

The proliferation of weapons of mass destruction by
rogue nations gave rise to a certain argument by scholars on preemption. They argued that the threat need not be "imminent" in the classic sense and that the illicit acquisition of the weapons, with their capacity to unleash massive destruction, by rogue states, created the requisite threat to peace and stability as to have justified the use of preemptive force.

Intention
The intention with a preemptive strike is to gain the advantage of initiative and to harm the enemy at a moment of minimal protection, for instance, while vulnerable during transport or mobilization
Mobilization (alternatively spelled as mobilisation) is the act of assembling and readying military troops and supplies for war. The word ''mobilization'' was first used in a military context in the 1850s to describe the preparation of the ...
.
In his "Rationalist Explanations for War," James Fearon attributes the use of preemptive strikes by rational states to both offensive advantages and commitment problems between states. When a nation possesses a first strike advantage and believes itself to have a high probability of winning a war, there is a narrower ''de facto'' bargaining range between it and an opposing country for peaceful settlements. In extreme cases, if the probability of winning minus the probable costs of war is high enough, no self-enforcing peaceful outcome exists. In his discussion of preventative war arising from a commitment problem, Fearon builds an infinite-horizon model expected payoffs from period t on are (pt/(l - δ)) - Ca for state A and ((1 -pt)/(l - δ)) - Cb for
state B, where Ca and Cb are costs incurred the respective states and δ is the state discount of the future period payoffs.
The model shows that a peaceful settlement can be reached at any period that both states prefer, but strategic issues arise when there is no credible third-party guaranteer of the two states committing to a peaceful foreign policy. If there is going to be a shift in the military power between states in the future, and no credible restraint is placed on the rising military power not to exploit its future advantage, it is rational for the state with declining military power to use a preventative attack while it has a higher chance of winning the war. Fearon points out that the declining state attacks are caused not by fear of a future attack but because the future peace settlement would be worse for it than in the current period. The lack of trust that leads to a declining power's preemptive strike stems not from uncertainty about intentions of different nations but from "the situation, the structure of preferences and opportunities, that gives one party incentive to renege" on its peaceful cooperation and exploit its increased military potential in the future to win a more profitable peace settlement for itself. Thus, Fearon shows that preemptive military action is taken by nations when there is an unfavorable shift in military potential in the future that leads to a shrinking bargain range for a peaceful settlement in the current period but with no credible commitment by the other party to avoid exploiting its improved military potential in the future.

is generally considered to be ''jus cogens'' (literally "compelling law" but in practice "higher international law") and prohibits all UN members from exercising "the ''threat'' or ''use'' of force against the territorial integrity or political independence of any state". However, in the modern framework of the UN Charter, it is the phrase "if an armed attack occurs" in Article 51 that draws the line between legitimate and illegitimate military force. Some scholars believe it is reasonable to assume that if no armed attack has yet occurred that no automatic justification for preemptive 'self-defense' has yet been made 'legal' under the UN Charter. Others conclude that the "inherent right of collective or individual self-defense" in Article 51 includes the preemptive, or anticipatory, self-defense recognized under customary international law, as articulated in the ''Caroline test' noted above. (See Self-defence in international law for additional discussion.) In order to be justified as an act of self-defense, two conditions must be fulfilled which are widely regarded as necessary for its justification. The first of these is that actor must have believed that the threat is real, as opposed to (merely) perceived. The second condition is that the force used in self-defense must be proportional to the harm which the actor is threatened.[David, and Henry Shue. ''Preemption: Military Action and Moral Justification''. New York: Oxford University Press, 2007. Print.]
