William McGurn: Bush's Real Sin Was Winning in Iraq - WSJ.com:

...In a few hours, George W. Bush will walk out of the Oval Office for the last time as president. As he leaves, he carries with him the near-universal opprobrium of the permanent class that inhabits our nation's capital. Yet perhaps the most important reason for this unpopularity is the one least commented on.

Here's a hint: It's not because of his failures. To the contrary, Mr. Bush's disfavor in Washington owes more to his greatest success. Simply put, there are those who will never forgive Mr. Bush for not losing a war they had all declared unwinnable.

Here in the afterglow of the turnaround led by Gen. David Petraeus, it's easy to forget what the smart set was saying two years ago -- and how categorical they all were in their certainty. The president was a simpleton, it was agreed. Didn't he know that Iraq was a civil war, and the only answer was to get out as fast as we could?

The chairman of the Senate Foreign Relations Committee -- the man who will be sworn in as vice president today -- didn't limit himself to his own opinion. Days before the president announced the surge, Joe Biden suggested to the Washington Post he knew the president's people had also concluded the war was lost. They were, he said, just trying to "keep it from totally collapsing" until they could "hand it off to the next guy."...

But it is far more than just being right about not surrendering to al Qaeda. The implications concern the Democrats surrendering of Southeast Asia to Stalinist tyranny and genocide...

...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...

Well, they were right to go ape over it. If the numbers could all be known it is likely that the Democrat Party has killed more people than Hitler.
