““In a world of terrorists, terrorist states and weapons of mass destruction, the option of preemption is especially necessary. In the bipolar world of the Cold War, with a stable non-suicidal adversary, deterrence could work. Deterrence does not work against people who ache for heaven. It does not work against undeterrables. And it does not work against undetectables: non-suicidal enemy regimes that might attack through clandestine means—a suitcase nuke or anonymously delivered anthrax. Against both undeterrables and undetectables, preemption is the only possible strategy.””
