Fireman Ryan,
Firstly, Iraq is a country, not our ward. It is not up to us to decide what is best for them. Besides, what makes us sure that we know what is best for them? If they were to vote us out, we should leave.
Furthermore, this is my opinion about setting up their gov't:
Why do Americans have so much pride in the American Revolution? Because we did it ourselves and developed a sense of identity, American Pride.
By setting up their gov't, I don't think they will truly appreciate it the way it should be appreciated. Which are you more proud of the shack you built or the shack someone else built for you?
So, if they don't have proper pride in it, then they wouldn't protect it above all costs, leaving room for another Saddam to come and take it away from them. Then the U.S. will have to go back and do the whole thing over again.
We are simply teaching them to depend on the U.S.
