If you haven't been reading his blog on a very regular basis, you really, really should be. I don't always agree with him politically (when he's serious), but he is ALWAYS thought-provoking and thinks everything through to great effect. I've come to love his thought experiments and Sunday posts in particular.
Go forth and read!
In this particular post (which is linked above), Scott takes on the ideas of what would happen if we were to "cut and run" in Iraq. And you know what? I agree with his ideas for the most part. Odd.
