In this Bloggingheads exchange, Heather Hurlburt of the National Security Network tries to explain why the U.S. has to fight in Afghanistan to keep Pakistan from imploding -- and expresses some surprise that Obama did not talk more about Pakistan in his West Point speech. Eric Posner quite effectively plays the bemused ordinary citizen who doesn't get the logic of "fight in Country A to stabilize Country B."
