Why really did George Bush jr. attack Iraq when there were no Weapons of m destruction?

Does anyone make a big deal when George Bush has given money to Africa,Indonesia,etc... for humanitarian reasons. No! We are a nation of givers and are The Guardians of Peace of oppression. In 10 years people will be eating their words because Iraq will be stabilized and flourish as a nation. I have seen the changes and although I have lost many brothers I believe we have done the right thing. If we only look at the negatives in life then that is sad.
