It's always the fault of those dirty liberals

Paul Krugman [behind subscription wall] has it about right:

Here’s how I see it: At this point, Mr. Bush is looking forward to replaying the political aftermath of Vietnam, in which the right wing eventually achieved a rewriting of history that would have made George Orwell proud, convincing millions of Americans that our soldiers had victory in their grasp but were stabbed in the back by the peaceniks back home.

What all this means is that the next president, even as he or she tries to extricate us from Iraq — and prevent the country’s breakup from turning into a regional war — will have to deal with constant sniping from the people who lied us into an unnecessary war, then lost the war they started, but will never, ever, take responsibility for their failures.
