The best thing I read today was this article by Robert Kagan over on RCP. It is way, way too long to comment on without writing an essay-length treatise. To give a vague summary, it lays out the author’s views on the present and future of international relations. You should read it. I don’t necessarily agree with all of his conclusions, but Kagan is a smart guy and the piece is very informative, regardless of any normative disagreements you might have.
