Here's a great read from realist Stephen Walt.

Q. How can you tell when William Kristol is giving bad policy advice?

A. His lips are moving. Or he's typing. Or he's writing an open letter for a bunch of hawks to sign. Or launching some new letterhead organization.

I refer, of course, to Kristol's recent op-ed in the Wall Street Journal (co-authored with the presidents of the the Heritage Foundation and the American Enterprise Institute). The basic theme is that the world is very, very dangerous, and so the United States should not cut a nickel from its defense budget, even though we already spend more than the rest of the world combined, have most of the world's major powers on our side, and possess a robust nuclear deterrent. So even though the country is also facing massive budget deficits, at least partly due to policies that Kristol has previously promoted, we need to build a wall around the defense budget and make sure it doesn't get shrunk. At all.
