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 shown that it intends to attack in the future, based on its past actions and posturing. A preventive war aims to forestall a shift in the balance of power by strategically attacking before the balance of power has had a chance to shift in the favor of the targeted party. Preventive war is distinct from preemptive strike, which is the first strike when an attack is imminent. Preventive uses of force "seek to stop another state . . . from developing a military capability before it becomes threatening or to hobble or destroy it thereafter, whereas [p]reemptive uses of force come against a backdrop of tactical intelligence or warning indicating imminent military action by an adversary." The majority view is that a preventive war undertaken without the approval of the United Nations is illegal under the modern framework of international law. The consensus is that preventive war "goes beyond what is acceptable in international law" and lacks legal basis. The UN High-level Panel on Threats, Challenges and Change stopped short of rejecting the concept outright but suggested that there is no right to preventive war. If there are good grounds for initiating preventive war, the matter should be put to the UN Security Council, which can authorize such action, given that one of the Council's main functions under Chapter VII of the UN Charter ("Action with Respect to Threats to the Peace, Breaches of the Peace, and Acts of Aggression") is to enforce the obligation of member states under Article 4, Paragraph 2 to "refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state . . . The Charter's drafters assumed that the Council might need to employ preventive force to forestall aggression such as initiated by Nazi Germany in the 1930s.
