wrong - see list of terrorism since 2001 - the US has stepped on a hornets nest

I hope you are joking. Here's a list of terrorist events PRIOR to us going into IRAQ and the "occupation" as you like to call it. Funny, I guess we're "occupying" Germany, Japan, Korea, etc because we still have bases there. We are in Iraq at the request of a FREELY elected Iraqi government. If they want us out, they will vote us out via the decisions of their parliament.
Terrorist attacks occurred before we went into Iraq and they would have continued if we hadn't. The question becomes, do you just sit back and take like we have for years or trying something else. Well guess what, we (and Blair, and Howard and others) decided to try something else.
By the way, since you used a hornets nest analogy, I don't know about you but when I see a hornets nest in my yard I don't let it just sit there...I TAKE IT OUT!
I can't even list them all because there is a 20,000 character limit on this message board...so here's the link.
