We're beginning to see that Ann Coulter's thesis about these people in the book Treason is correct.
The United States has a huge strategic interest in being in Iraq. We needed to remove an Arab dictator, to show the other Arab dictators that it could be done. We needed to shift our base of operations from a hostile country, Saudi Arabia, to a newly created Arab democracy. We needed to remove any possibility that Iraq would be used as a base for terrorist operations, and a source of materials for terrorists. The operation also destabilised the dictatorship in Iran. These are four huge strategic goals achieved for America, and we nailed a sadistic, vicious mass-murderer to boot.
Katie Couric would have attacked the Normandy invasion as unjustified if she'd been around in 1944.
I'll give her the benefit of the doubt on that. We were saving the French, after all ;-)
