I think it's a combination of both tighter security in the American homeland (we've caught many people trying to do terrorist things) and also Al Queda fight against US troops in Afghanistan and Iraq, instead of coming to America.

Like Bush said, our wars in Afg. and Iraq are like a magnet to the terrorists, better to fight them over there then over here.

ALso i think Al Queada is mostly now hiding out in the rural areas of pakistan near the Afghan border, so it's easier for us to kill thenm with Drones, and not have to risk any American lives in the battle.

The civilian cost is unfortunate, but at least it's not an American civilian cost.

That being said, i do believe there will be another major islamist attack on US soil within our lifetime. Nothing as big as 9/11 though, i don't think. Probably more like the 7/7 london bombings.
