http://en.wikipedia.org/wiki/Brinkmanship The leaders in Iran are now practicing classic brinkmanship "diplomacy" using the threats available to them to finish developing a nuclear weapons. If all the world powers (including Israel) are not satisifed and cooperate with a plan to isolate Iran econmically we assuredly see some form of miltary effort to set back if not destroy Irans' bid for nuclear weapons. With Irans ability to control oil supply, do Russia and China really care if Iran has a nuke? I doubt it since it wont be aimed at them and both countries stand to lose billions if Iran is effectively isolated. A difficult situation indeed since success rides on the cooperation of countries with very different ideologies and concern. It will be interesting to see how it plays out with a few wild cards in the mix.
