In Preemption one of our nation's foremost legal scholars puts forward a controversial new theory on crime and punishment in the postmodern world. Using the American government's 2003 invasion of Iraq as a starting point, Alan M. Dershowitz tracks our society's increasing reliance on preemptive action. In Preemption, which Judge Richard Posner of the U.S. Court of Appeals calls lucid, sober, courageous, and historically informed, Dershowitz has brought together all of his diverse and considerable talents and experiences to confront the idea of preemptive action as it applies to some of our most urgent political and moral dilemmas.
