It is against International Law to rip a country apart, then leave it in worse shape than you found it. We are required to help rebuild.
We appropriated $68 billion of our own money to rebuild Iraq, hired the contractors, and set them to work. If Iraqis keep slaughtering our guards and contractors instead of letting them work, this is in no way our problem. We have given Iraq until June 30 to let us rebuild; if they won't, then Im hoping we cut back our presence on that date to a few large military bases, from which we will launch whatever strikes against terrorists in the region we feel like.
