Bush applied the same intelligence analysis, Congress agreed, and decided to end Saddam's rule
If the intel was mistaken about WMDs, it was mistaken for many years.
I think most Americans are alright with the war, understand that it was fought for the same reasons Clinton bombed Iraq and sustained the sanctions, and that 911 proved that simply waiting terrorists out only gives them the opportunity to corrupt weak states and use those resources to kill more victims.
Before running for Pres., most democrats understood this.
And the fact that Libya had a substantial nuke program totally hidden from view and only decided to end it after the example of American resolve, should give pause to the left.
And if that is not enough, then the outting of the BBC and the vindication of Tony Blair for the use of the same intel, should.
