White House speechwriter Marc Thiessen was locked in a secure room and given access to the most sensitive intelligence when he was tasked to write President George W. Bush’s 2006 speech explaining the CIA’s interrogation program and why Congress should authorize it. Few know more about these CIA operations than Thiessen. In his new book, Courting Disaster, Thiessen documents just how effective the CIA’s interrogations were in foiling attacks on America, penetrating al-Qaeda’s high command, and providing our military with actionable intelligence.
