At least some Bush administration officials had opposed the interrogation techniques, including notably Condoleezza Rice’s most senior adviser Philip Zelikow.[55] Upon learning details of the program, Zelikow wrote a memo to Rice contesting the Justice Department’s Torture Memos, believing them wrong both legally and as a matter of policy.[55] Zelikow’s memo warned that the interrogation techniques breached US law, and could lead to prosecutions for war crimes.[26][56]The Bush Administration attempted to collect all of the copies of Zelikow’s memo and destroy them.[55][57][58] Jane Mayer, author of the Dark Side,[59] quotes Zelikow as predicting that “America’s descent into torture will in time be viewed like the Japanese internments”, in that “(f)ear and anxiety were exploited by zealots and fools.”[60]
