What makes you think Iran will conclude that one of the determinant variables is nuclear capability? From a game theoretic perspective that's a pretty huge leap. edit: to rephrase, what evidence is there that Iran's actions are based upon the conclusion that the current push towards peace on the Korean peninsula (which is also being pushed by China, South Korea, and Japan, in addition to the US) would not be happening if not for the nuclear capability developed by North Korea?
