You mentioned Churchill and others. I've been waiting and waiting for something to come from the mouths of those on our side to produce something memorable or quotable in a historical sense. Let me try a few out on you:
"Uniformed or not, our soldiers will waste no time with insurgence."
"Try as they might, neither a woman's skirt nor minoret shall provide safe harbor.
"Don't mess with budwiesest."
BS. He is delivering the "goods". He has never wavered on this from 911 to date. Just because you and many others have caved doesn't mean he has "lost his way". He has a hell of a lot more to lose on this than any of us. BTW, the decision on Falujia was made by the Marine commander on the ground. Bush has let the military conduct this war unlike what happened in Viet-Nam.
It sounds as if you're looking for a soundbite. The President delivered a comprehensive speech.
