Because the US goverment is only intrested in money. The resources that could be gained from take overs of the Middle Eastern countries would be great. The region is loaded with oil and the such. And the US goverment is attracted to this resource like a fly to a lollypop. This is why 9/11 and the such have been speculated many a time. Because of the fact that Mr Bush wanted to invade Iraq at the time and after 9/11 he got the support he needed to start a invasion. And Iraq is a country with great oil business. In way its all a neverending circle. The US fights, makes money, uses money for miltary, fights, makes money, uses money for miltary, etc etc. Its a never ending circle of blood and death just for cash. Though they do need the money since the dollar is practically worthless, worth less then half a quid.
