It seems that Bush's main selling point on Iraq today is that we can't afford to let his policy fail. What he really means is that he can't afford to admit that his policy is already failed. He also seems unable to allow that the American people, and more importantly the Iraqi people have had their say, or that their opinions matter.
BTW, why have I heard so much about how the Bush Administration is reacting to the ISG report, but nothing from Muqtada al Sadr, for example, or any other Iraqi? If the ISG is offensive to Iraqis, isn't the effort stillborn as a serious policy proposal?
