Simply put, there are those who will never forgive Mr. Bush for not losing a war they had all declared unwinnable…

This is Vietnam thinking. And the president never accepted it. That was why his critics went ape when, in a speech to the Veterans of Foreign Wars, he touched on the killing fields and exodus of boat people that followed America’s humiliating exit off an embassy rooftop. As the Weekly Standard’s Matthew Continetti noted, Mr. Bush had appropriated one of their most cherished analogies — only he drew very different lessons from it.

Mr. Bush’s success in Iraq is equally infuriating, because it showed he was right and they wrong. Many in Washington have not yet admitted that, even to themselves. Mr. Obama has. We know he has because he has elected to keep Mr. Bush’s secretary of defense — not something you do with a failure.
