HRC's Foreign Policy Mission Statement

What is it with this week and really long essays on foreign policy? First there was the Joshua Muravchik's piece in Commentary, then the Barry Posen article mentioned earlier, now Hillary Clinton's candidate essay has appeared in Foreign Affairs. I'm not going to bother with right now (it being quarter after midnight, and all), because I would like the opportunity to read it side by side with Rudy Giuliani's essay published earlier this year, and which was roundly criticized by many when it appeared in August.
