The scary thing is, this is the best spin Karl Rove's editors could put on the National Intelligence Estimate:
Analysts assess that al-Qaeda "will probably seek to leverage the contacts and capabilities of al-Qaeda in Iraq, its most visible and capable affiliate and the only one known to have expressed a desire to attack the Homeland".

Bush's "fight them over there" decision to invade Iraq has allowed Al Qaeda to move to the tribal areas in Pakistan, re-establish their network, and generated a "visible and capable affiliate" eager to attack the United States. According to the Republicans, this means we should "stay the course."
There was another George who thought the "will to win" guaranteed victory - George Armstrong Custer. One wonders whether he thought anyone opposing his idea to split up his command and stage a daring attack without adequate advance intelligence or back-up planning just "didn't support the troops."
