Preemptive war
A preventive war is one in which a country attacks another in order to prevent them from having the capability of making war. A preventive war is one based on the idea that it is possible to tell with certainty the events that will take place. Article 51 of the United Nations Charter recognizes “the inherent right of individual or collective self-defence if an armed attack occurs”. For example, under the Bush Doctrine, the United States may attack any nation or group that may attack the country in the future even if it does not currently have that capability. By calling it "preemptive", it does not change if from being preventive.
