I think the succesful manner in which we have been taking it to the terrorists has gone a long way in not having any more serious attacks on the U.S. Some shootings (Utah mall) and some vehicle vs. pedestrian attacks may have been motivated by Islamic hate - but not a coordinated or serious effort.
But - the lack of terrorist attacks is what I fear will make our new leaders complacent.
That certainly seems the case for the Dhimmicrats, who have returned to their 1970's/80's groove of isolationism and pacifism. McCain seems to get this one.
Keeping Osama and party bottled up in Northwest Frontier seems seriously to have degraded A.Q. The left won't admit it, but Iraq has damaged A.Q. hugely. The spectacle of A.Q. killing their own, especially Sunnis, in Jordan and Iraq (and Lebanon) has really damaged them throughout the Muslim world, not to mention they've now been defeated on two battlefields.
