So what is Bush's leverage with the Iraqi government?

Bush is basing his entire future in the history books on Iraq, so how likely is he to put any pressure at all on the Iraqi government? He so desperately wants to show some success in Iraq that it is doubtful that he will somehow suddenly find the ability to get tough now. Sounds like more wishful thinking and hope instead of tough policy and the only legitimate tough talk is coming from the Democrats. Wishful thinking will not win a war that has spiraled out of control long ago.

What makes this new plan any different from every other tweaking over the last 3 1/2 years and once again, why should we believe Bush now? His credibility is at rock bottom and everyone knows it so expect more of the same.
