Former Defense Secretary Donald Rumsfeld has very few regrets, according to his new book Known and Unknown: A Memoir. His biggest regret, he writes, is not quitting after the Abu Ghraib prison abuse scandal. However, he has no regrets about the Iraq War, writing that "the Middle East would be far more perilous than it is today" with Saddam Hussein in power. Rumsfeld notes that two letters of resignation he wrote to President George W. Bush were rejected. He also unleashes criticism at members of Bush's cabinet, including former Secretary of State Condoleezza Rice and her predecessor Colin Powell, as well as Presidential Envoy to Iraq Paul Bremer. "There were far too many hands on the steering wheel, which in my view was a formula for running the truck into a ditch." Rumsfeld's memoir is due for release next week.
