Which is exactly what was predicted:

"That's a very volatile part of the world. And if you take down the central government in Iraq, you could easily end up seeing pieces of Iraq fly off. Part of it the Syrians would like to have, the west. Part of eastern Iraq the Iranians would like to claim. Fought over for eight years. In the north, you've got the Kurds. And if the Kurds spin loose and join with Kurds in Turkey, then you threaten the territorial integrity of Turkey. It's a quagmire if you go that far and try to take over Iraq." -- Dick Cheney
