With the Iraqis now calling for U.S. troops to leave, the Bush-McCain war effort is falling apart.

Even though both Bush and McCain said in the past that we would leave if the Iraqis want us to, they are now furiously trying to find a way out of this political mess.

There is a rather large elephant standing in the room here. So many people believe that Bush-McCain want to stay in Iraq because of oil. That might be partially true, but there is something even bigger at work here.

If America leaves, Iran will likely move in. Bush-McCain do not want to admit that the government they helped install in Iraq, selected by the Shia majority that they helped free from Sunni domination, is closely allied with Iran. If America pulls out, the Iranians would be happy to help their Iraqi friends keep the peace, and protect the Shia government.

If Iran moves in, then the defeat will be evident to everyone. Even if violence drops to nothing, to the point where even McCain couldn't make the case for staying, it benefits Iran far more than us.
