Glenn Greenwald’s thesis here is pretty straightforward. 

First, Glenn notes that conservative Bill Kristol pointed the finger at the U.S. military, as an explanation of the Iraqi debacle.  Kristol got the blame game started, and now that it’s in full swing, Glenn plays it himself.

Glenn then turns to blogger Jeff Goldstein, who "shared this blame-shifting gem with us yesterday":

One of the important points made in this excerpt (the entire piece is available to subscribers only) is that a goodly portion of our success or failure in Iraq has ultimately to do with how we react in terms of either lending our support or leveling our criticisms against the campaign.

And this is (and has been) a crucial component of the war—one that many on the anti-war side are loathe to admit: that their constant naysaying, though it is well within their right to voice, has objectively hurt the war effort, particularly when the criticism incorporates carefully-crafted falsehoods many of the war’s critics know for a fact to be objectively untrue.

From my perspective, there comes a time when, having registered disagreement with the war, the war’s critics (and here I’m not talking about critics of individual strategical or tactical initiatives, but rather those who have been against the effort from the start) simply wait and—if things fail—rush to brag of their prescience and perspicuity. But in the meantime, actively working to undermine the effort by presenting our enemies with a rabidly partisan divided front (one of their chief aims, remember)—whether it be through suggestions that we are in Iraq “illegally”, or that the President “lied” to take us to war, or seemingly hoping, on a daily basis, that the whole thing devolve into a civil war—matters. And not just rhetorically.

Greenwald mockingly responds:

One can bet the mortgage that we’ll be seeing a lot more of this over the next few months – between now and, say, oh, November or so. Those who insisted on this war, who started it, who prosecuted it, who controlled every single facet of its operation – they have no blame at all for the failure of this war. Nope. They were right all along about everything. It all would have worked had war critics just kept their mouths shut. The ones who are to blame are the ones who never believed in this war, who control no aspect of the government, who were unable to influence even a single aspect of the war, who were shunned, mocked and ridiculed, and who have been out of power since the war began. They are the ones to blame. They caused this war to fail.

Glenn is absolutely right.  How can the failure of the Iraqi effort be blamed on those who are NOT in power, and who control NO branch of government?  Read it all.
