Hugo Grotius, the 17th century jurist and father of public international law, stated in his 1625 magnum opus The Law of War and Peace that "Most Men assign three Just Causes of War, Defense, the Recovery of what's our own, and Punishment."

Overview

Chapter VII of the United Nations Charter

Article 51 of the UN Charter states the following:

Article 51: Nothing in the present Charter shall impair the inherent right of collective or individual self-defense if an armed attack occurs against a member of the United Nations, until the Security Council has taken the measures necessary to maintain international peace and security. Measures taken by members in exercise of this right of self-defense shall be immediately reported to the Security Council and shall not in any way affect the authority and responsibility of the Security Council under the present Charter to take at any time such action as it deems necessary in order to maintain or restore international peace and security.

International law recognizes a right of self-defense, as the International Court of Justice (ICJ) affirmed in the Nicaragua Case on the use of force. Some commentators believe that the effect of Article 51 is only to preserve this right when an armed attack occurs, and that other acts of self-defense are banned by article 2(4). The more widely held opinion is that article 51 acknowledges this general right, and proceeds to lay down procedures for the specific situation when an armed attack does occur. Under the latter interpretation, the legitimate use of self-defense in situations when an armed attack has not actually occurred is still permitted. It is also to be noted that not every act of violence will constitute an armed attack. The ICJ has tried to clarify, in the Nicaragua case, what level of force is necessary to qualify as an armed attack.

Right to Personal Self-Defense as a General Principle of Law recognized by Civilized Nations

Apart from self-defense in interstate relations, international law also recognises a right to personal self-defense as a general principle of law recognized by civilized nations pursuant to Art. 38 (1) (c) ICJ Statute.[1] This right follows from the fact that all major domestic legal systems as well as the major natural law traditions of the world all recognise self-defense. The principle finds practical application e.g. in international humanitarian law, where a civilian may exercise personal self-defense against atrocities without being considered a direct participant in hostilities. In human rights law, personal self-defense (and defense of others) against an imminent threat to life constitutes the only justification for law enforcement agents to use deliberately lethal force ("shooting to kill").[2]

Customary international law and Caroline test

The traditional customary rules on self-defence derive from an early diplomatic incident between the United States and the United Kingdom over the killing of one US citizen engaged in an attack on Canada, then a British colony. The so-called Caroline case established that there had to exist "a necessity of self-defence, instant, overwhelming, leaving no choice of means, and no moment of deliberation,' and furthermore that any action taken must be proportional, "since the act justified by the necessity of self-defence, must be limited by that necessity, and kept clearly within it." These statements by the US Secretary of State to the British authorities are accepted as an accurate description of the customary right of self-defence.[citation needed] (Dan Webster, Yale Law School)

Imminent threat

The imminent threat is a standard criterion in international law, developed by Daniel Webster as he litigated the Caroline affair, described as being "instant, overwhelming, and leaving no choice of means, and no moment for deliberation." The criteria are used in the international law justification of preemptive self-defense: self-defense without being physically attacked first (see Caroline test). This concept was introduced to compensate the strict, classical and inefficient[how?] definition of self-defense used by Article 51 of the Charter of the United Nations, which states that sovereign nations may fend off an armed attack until the Security Council has adopted measures under Chapter VII of the United Nations Charter.

The Caroline affair has been used to establish the principle of "anticipatory self-defense" and is also now invoked frequently in the course of the dispute around preemptive strike (or preemption doctrine).

President of the United States of America Barack Obama and his administration has defined "imminent" to mean that have 60 days to find and kill an individual human being. Under this theory of law "imminent" therefore means that a threat over, at least, up to 60 days (2 months) in the future is considered "imminent". In human rights law, personal self -defence imminence requires close temporal proximity, i.e. the person targeted must be ready to strike. [3]
