With yesterday's apparent nuclear test in North Korea, foreign policy again comes back to center stage. And fortuitously this week, TPMCafe Book Club is discussing the new Princeton Project on National Security's final report: "Forging a World of Liberty Under Law, U.S. National Security In The 21st Century."

Participating in the discussion are John Ikenberry, Anne-Marie Slaughter, Daniel Drezner, David Rieff, Stephen Walt and Peter Trubowitz
