Regarding Khomeini - dictators end up where they didn't expect. Tell Stalin of 1923 that he'll end up shooting all his buddies while calling them Japanese spies with plain face. Tell young Khomeini that his main achivement will be aforemendioned redressing. Tell Putin of 2001 that he'll turn out a longer-lived mummy than Brezhnev. They'd have a healthy laugh back then.
