The Iranian issue I don't think has much to do with nuclear weapons frankly. Nobody is saying Iran should have nuclear weapons ­nor should anybody else. But the point in the Middle East, as distinct from North Korea, is that this is center of the world's energy resources. Originally the British and secondarily the French had dominated it, but after the Second World War, it's been a U.S. preserve. That's been an axiom of U.S. foreign policy, that it must control Middle East energy resources.
