What President Bush knows, Is that these people are not going to stop until they've exterminated us. They flew planes with children on them (a 2 month old baby on one of them) into a buildings ,knowing full well that every one would be killed. The icing on the cake is that they actually beleive they are going to heaven for their deeds! We don't have to bother with airport security. The next attack will be biological chemical or nuclear. I doubt if these nut cases will do the same thing twice. Is 10,000 innocent dead people not enough for you? How many dead people are enough? What would you think we should have done about Hitler?
As for Hitler, they were too slow to act against him. They tried appeasement. They are still trying appeasement here in Northern Ireland.
If you want to see how Bush could botch it look at the fate of Dresden in 1945.
