Hamas Victory

I was wondering the other day as news about the Hamas vistory is still a main story in the media, whether the US simply wants absolutely everything to go their way in the Middle East? For logical reasons, I think the government does have a right to support whoever they think is the best governing body, but I also have to wonder what they will do with every governing body that they dislike or disagree with. Condaleeza Rice time and again says that the US will cut all financial and political support of the country unless the governmental choice is reevaluated. I wonder what is going to happen if Hamas does not step down.
