Iran is already a nuclear weapons state with enough uranium to build ‘one, if not two’ bombs, an ex-US diplomat and nuclear weapons expert has warned. Former Washington official Robert Joseph said, ‘The International Atomic Energy Agency (IAEA) has documented that Iran has 60% of enriched uranium, enough for at least one if not two bombs. ‘We have been saying for years “they’re approaching this breakout point and we’ve really got to negotiate with them.” They’re there.’
