Questions are being asked in Washington if the world is a more dangerous place now than it was during the Cold War. Pakistan has gone from America’s key ally in the War on Terror to being on the cusp of a full blown civil war and North Korea has carrie dout yet another nuclear test accompanies with a warning that it would no longer respect the 1953 Armistice agreement that until now has kept peace on the Korean Peninsular.  There is far more danger in dealing with rogue and failing states than there is with nuclear-armed mature states. War in Pakistan has become a reality. So far North Korea’s hostility has been confined to missile diplomacy — but that could flip at any time.
