Military strategists analyze Khamenei's personality to determine how he would act in a crisis situation. US National security officials believe, Khamenei doesn't entirely trust the international system... but he's not extremely reckless either. The problem with trying to assess people in leadership positions. Is that we're dealing with complex human being. Able to re-assess situations and capable of changing their mind. John Limbert, a former US diplomat met Khamenei in 1980 when he was held hostage in Iran for 444 days. He believes the Iranian Clerical elite over-arching concern is power and stability. He said... 'for Khamenei... the priority is political survival'. One has to wonder whether a nuclear arsenal would provide the stability the Ayatollahs desire for the Islamic Republic.
