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 definition of self-defense used by Article 51 of the Charter of the United Nations, which states that sovereign nations may fend of an armed attack until the Security Council has adopted measures under Chapter VII of the United Nations Charter.
