"Iran may have a nuclear weapon soon if Washington and Moscow do not unite to slow its efforts. The collapse of the Soviet Union created new complications in a long tradition of nonproliferation cooperation between the United States and Russia, and Iran is just one example. In the 1960s, faced with a common nuclear threat of China, Washington and Moscow united to negotiate the Limited Test Ban Treaty and Nuclear Nonproliferation Treaty to prevent China and other nuclear aspirants from proliferating nuclear weapons. They shepherded their allies to the nonproliferation table and made them sign the treaties. Their efforts retarded nuclear proliferation but failed to prevent China, India, and Pakistan, from gaining nuclear weapons. Following the Cold War their cooperative relationship changed as Washington began treating Moscow as an unequal partner and their nonproliferation efforts broke down into a cooperative and uncooperative mix. This mix has reduced the effectiveness of their efforts and may accelerate proliferation. The September 11th terrorist attacks put more attention on the nuclear proliferation threat to the international community. If this threat is to be minimized, Washington and Moscow need to work together, as they did against China, to prevent new nuclear powers from emerging."
