Abstract/Summary

This Article explores the appropriateness of preemptive strategies in international law. Are preemptive actions approved by the international community lawful? Can States act unilaterally or in a coalition of the willing to preempt terrorism, the development and transfer of WMD, or other threats? If so, under what circumstances and based on what quantum and quality of evidence? When can preemptive actions be taken against non-State actors such as terrorists who are based in other States?
