There is a lot left to do in Iraq, we have to stablize the region or its going to become a terrorist hotzone and wreack havoc all over the world. Iraq may not have had WMDs in 2003, but they did have them at one point so it wasn't a stretch to think that they still had them somewhere. We just can't leave a let them kill each other, because than Iran would invade. Once Iran got control of Iraq, they would likely join forces with Syria and possibly Jordan to attack Isreal. which means the US, and most other NATO/UN countries would be back over there. but we wouldn't be fighting just sparce pockets of terrorist, but a highly trained and highly moble military force with control of most the worlds oil. with them in control of the oil, the US would need to dip into our own reserves, which means the government would limit the ammount of oil availble to the public. The re-invasion of the middle east would likely cost tens of thousands of lives.We must stay, we must stablize Iraq, and we must help build them a military. This war was never about oil, if Bushco wanted oil, they could have invaded Kuwait, Mexico, Venezula, Canada, Alaska, Texas, Utah, or New Mexico a lot easier and a lot cheaper. The war was either done because Bushco honestly believed that Iraq posed a threat to the US, or it was vengence for Saddam trying to assassinate George HW Bush.
