On December 2, 2002 the U.S. Secretary of Defense, Donald Rumsfeld, signed his name at the bottom of a document that listed eighteen techniques of interrogation--techniques that defied international definitions of torture. The Rumsfeld Memo authorized the controversial interrogation practices that later migrated to Guantanamo, Afghanistan, Abu Ghraib and elsewhere, as part of the policy of extraordinary rendition. From a behind-the-scenes vantage point, Phillipe Sands investigates how the Rumsfeld Memo set the stage for a divergence from the Geneva Convention and the Torture Convention and holds the individual gatekeepers in the Bush administration accountable for their failure to safeguard international law.
