Karl Rove has a new memoir revealing his regrets from the Bush administration:

Republican strategist Karl Rove says in a new memoir that the failure to find weapons of mass destruction in Iraq badly damaged the Bush administration's credibility and led to dwindling public support for the war.

Okay, this is good! Going to war against a country to stop their use of WMDs when in fact they didn't have any WMDs turns out to be a poor foreign policy. We're learning!

Oh, wait -- the story continues:

The former White House political adviser blames himself for not pushing back against claims that President George W. Bush had taken the country to war under false pretenses, calling it one of the worst mistakes he made during the Bush presidency.

So the problem is not that Bush took the country to war on the basis of faulty intelligence, but that Rove was insufficiently vicious in attacking people who pointed this out. Hmm. Maybe returning these people to power at this point is not such a good idea.
