You sir, are an a$$hole. I know a good handful of Europeans, and it seems they don't share your sentiments. In fact, it seems like the only people that do are Bin Laden and Iraq.
I'd like to see some hijackers take over and kill 20k of your people, some personally known and related to you, then see how joyous you are.
There has been no credible evidence that our air force shot down our own civilian plane. In fact, evidence now points that a handfull of the people on board flight 93 struggled to retake the plane from the COWARDLY and DESPICABLE terrorists. They seem to have retaken the plane, and knowing they were going to die, decided to crash the plane in an unpopulated region instead.
Oh, and for being pussies, after they slit a couple stewardess' necks, you see how inclined you are to fight back. And most hijackers don't crash the plane intentionally; most just want the pilot to fly to a certain destination.
And now that Article 5 has been passed, the US has all of NATO's backing, I guess all of Europe isn't laughing at us. They're actually backing us. "An attack against one is an attack against all."
