Therefore, I don't think that the current leadership has any interest in making a liberal shift themselves.  I am convinced that they are bent on nukes, and I don't see any viable ways of stopping them. Talking won't do any good, unless/until an unforeseen event changes the calculus and creates an opening.  In the meantime, the best we can do is contain them.  And change will come to this leadership.  These mullahs are old, and if the people of Iran are unable to change the government, then generational change will.
