The Sept. 11, 2001, terror attacks by al-Qaida were meant to harm the United States, and they did, but in ways that Osama Bin Laden probably never imagined. President George W. Bush's response to the attacks compromised America's basic principles, undermined its economy, and weakened its security.

The attack on Afghanistan that followed the 9/11 attacks was understandable, but the subsequent invasion of Iraq was entirely unconnected to al-Qaida—as much as Bush tried to establish a link. That war of choice quickly became very expensive—orders of magnitude beyond the $60 billion claimed at the beginning—as colossal incompetence met dishonest misrepresentation.
