The vast majority in here would undoubtedly choose the US because our system is far more compassionate, more free, and more fair than Al Qaeda's.
Hell, no one can disagree with that. But we shouldn't have to compare ourselves to the shitheads AQ is to see ourselves as great. It's like me comparing myself to a homeless person so I can feel wealthy.
But we don't play fair overseas. We aren't compassionate nor fair when it comes to our foreign policy, and we certainly aren't always on the side of freedom and democracy. Now, sure, countries do normally act in their own self-interest, but what happens when the "world's policeman" acts in this manner? We're seen as the great hypocrites we are. And we are hated and despised for it. What we do overseas is not making us safer at home, in fact it does the opposite. Our own foreign policy is probably the biggest danger to our own national security.
This idea that AQ or their ideology could take over the ME is completely absurd. The people of the ME don't like them either. With maybe a couple of small exceptions, they've been run out of every country they've tried to set up camp. The most significant exception to this is Afghanistan and that could not have been possible without US aid.
Like Craig has above, one could ponder on their untold motivations. Regardless, we need not continue feeding them ammo. Our actions only aid their recruiting. And that not only endangers us, it endangers the rest of the world, too.
