`  == Reason For Iraq Invasion? ==    A bunch of friends and i have been carefully trying to follow the war and the progress of the U.S.A. in Iraq. However, we are extremely confused to why they invaded in the first place. I have read many articles and have herd many theories regarding the invasion. I am from Canada and we have not sent any troops to aid the U.S.A in Iraq, but we have sent troops to Afghanistan to help out. In my understanding, it was Afghanistan who attacked the U.S.A in 9/ 11, right? So we have NATO, United States, United Kingdom, Canada, Australia, France, New Zealand, Italy, and Germany stationed in Afghanistan. My question is: why are the Amercians in Iraq if it is Afghanistan who has attacked them?  I am sory this is such a dumb question i was just hopeing someone could give me an educated answere other then ``because Saddam is a jerk``. I was also wondering why other countries have not joined the U.S.A in Iraq if it is as seriouse as i've been hearing. Thanks!`
