The world today is overwhelmed by wars between nations and within nations, wars that have dominated American politics for quite some time. Point of Attack calls for a new understanding of the grounds for war. In this book John Yoo argues that the new threats to international security come not from war between the great powers, but from the internal collapse of states, terrorist groups, the spread of weapons of mass destruction, and destabilizing regional powers. In Point of Attack he rejects the widely-accepted framework built on the U.N. Charter and replaces it with a new system consisting of defensive, pre-emptive, or preventive measures to encourage wars that advance global welfare. Yoo concludes with an analysis of the Afghanistan and Iraq wars, failed states, and the current challenges posed by Libya, Syria, North Korea, and Iran.
