Have you considered that maybe there hasn't been so much fighting over here because we have a military that could completely curbstomp anyone if they try? There's also that issue of Pearl Harbor, where we tried to be neutral and they dragged us into it anyways. Then there's also 9-11, unless you are one of the truthers.
A woman sits down next to a man on a Stockholm park bench. Every so often, the man picks out a whistle and blows it. After a while, the woman ask him "Why are you blowing that whistle?"
"To scare away the tigers."
"How do you know it works?"
"Well, have you seen any tigers around?"
Correlation and causation et al. Sweden hadn't been in a war for over 200 years before we invaded Afghanistan with NATO, and it's not like we don't have desirable resources (iron and uranium for starters) or had an unimportant strategic position, and we were neutral for most of those years, with only a tangential relation with the US/NATO after WWII. And nobody invaded us either.
And besides, most of the governments over there are directly funding the terrorists anyways.
And the US is directly or indirectly funding many of those governments.
If I have to choose between their survival and ours, I think I know which one I'm going for.
There is no real reason you should live when they don't. Besides, that was never the choice anyway.
Perhaps leaving them to their own devices AGAIN was a mistake. It never worked. As soon as the occupying force pulls out, they just go back to doing what they were doing before, fucking with everyone else. The region is inherently unstable and dangerous, it seems.
edit: it's been like this for hundreds of years.
You never left them to their own devices. The US put Saddam Hussein in power. The US funded the proto-al Quaida organisation. The US overthrew the democratically elected Iranian government and installed the Shah.
Every single problem the US, and the world, now faces in and from that region stems from American, and before that Brittish, interference in the region.
