President Bush's biggest regret of his presidency is receiving faulty intelligence before launching the Iraq war, the president told ABC News in a wide-ranging "exit interview." Bush declined to say whether he would have ordered the invasion if he had known Saddam Hussein didn't actually possess weapons of mass destruction. "That is a do-over that I can't do," he said. "It's hard for me to speculate."
Bush said his greatest achievement as president was fighting "a war against ideological thugs." The president said he didn't spend a lot of time worrying about what history would think of him, but that he hoped he would be remembered as somebody who came to Washington and never compromised his principles. "I will leave the presidency with my head held high," he said.
