Pundits, and some of the blogosphere, want there to be a neat left/right split on whether to invade Iraq. So, we've heard a lot of liberal arguments against an invasion and lots of conservative arguments in favor of an attack. As I've previously said , however, there are good liberal reasons for invading Iraq. And there are good realpolitik reasons for opposing an invasion.

The problem is, it's been too easy for conservatives to ridicule the anti-war argument because it usually comes with the whiff of anti-Americanism (Chomsky) or political failure (Gore). [What about Michael Walzer? -ed. There's him and... er, no one].

I have it on good authority that we're going to hear more about the realist argument against attacking Iraq very, very soon.
