Daniel W. Drezner teaches international politics at Tufts University’s Fletcher School of Law and Diplomacy and blogs about the same topic at Foreign Policy. You don’t need to be an expert on the subject to find his work rewarding. He’s adept at explaining tricky matters in a clear, concise and engaging fashion. He also links to worthwhile posts elsewhere, whether he agrees with them or not. And his far-flung approach to his topic even lets him review bad prime-time TV shows.
