Today, Atrios quotes an article Condolezza Rice wrote in 2000 that basically says everything the administration is doing in Iraq toay is doomed to failure. But afterwards, he hits the phrase everyone should be repeating:

Look, for too long these people have swept this stuff aside by chanting "9/11 changed everything." No, 9/11 didn't change everything. What 9/11 did is prove that these people were wrong about absolutely everything. And, what Iraq has proven is they still haven't learned anything.

That's it right there, and needs lots of airtime:

9/11 didn't change everything. 9/11 proved the neocons were wrong about everything.
