Yeah, I agree - The time table I suggested is a bit too optimistic. Taking into account how clumsy and ineffective international politics is.

What you don't seem to recognize though is that nations haven't been willing to join the Bush/US led coalition. That doesn't mean countries aren't willing to send troops under the UN banner to solve the mess the neo-cons have made. UN peace keepers are in numerous places around the world and Iraq is certainly the place where they needed the most. It's very unlikely though as it would require Bush to humbly admit his failure and give over the job to the organization he BS'ed.

The situation now is that anything goes. Chaos is victory for the enemies of the American occupation... and it does take the form of "tribal" rivalry as well as violence against the American troops etc.
