Matt Yglasias cuts to the quick in revealing exactly how Bush's Iraq misadventure lacks any sort of clarity.

The Wages of confusion. Bush today:

If America were to pull out before Iraq can defend itself, the consequences would be absolutely predictable — and absolutely disastrous. We would be handing Iraq over to our worst enemies — Saddam's former henchmen, armed groups with ties to Iran, and al Qaeda terrorists from all over the world who would suddenly have a base of operations far more valuable than Afghanistan under the Taliban.

I and everyone else have been complaining awhile about Bush's habit of conflating various groups. We see here, though, that this isn't just some matter of intellectual fastidiousness. The idea here is that absent the US military, we would be handing Iraq over to some nefarious -- and, admittedly, it would be quite nefarious -- coalition of Baathists, Iranians, and al-Qaedists, presumably joined by Dr. Evil and the Cobra Commander. Back in the real world, though, these groups are fighting each other. What's more, the "armed groups with ties to Iran" include the political parties that comprise the Iraqi government. So what is it our troops are accomplishing amidst this frothy mix of bad actors?

There's no strategy here.  None.  Iraq, from the beginning has been about politics, not policy.  The aim of the adventure is to preserve Bush and his political helpers.  Literally, it is party before country.
