Paul Krugman's latest column discusses how President Bush's actions have ended up bolstering terrorist movements throughout the world; its a good read, but it contains this eyebrow-raising aside:

At the same time, [he] would neglect the pursuit of those who attacked us, and do nothing about regimes that really shelter anti-American terrorists and really are building nuclear weapons.

Attacking President Bush for his supposed inaction on Iran and North Korea has been a favorite liberal technique as of late - Bill Maher and others have been making this case on the news channels for a while now. The argument, though, reeks with hypocrisy; liberals have advocated a multi-lateral approach based on negotiation with Iraq; why are they suddenly unhappy this approach is being pursued in regards to Iran and North Korea?
