Mousavi is not Khomeini, and Khamenei is not the Shah. Meaning, Khomeini would not hesitate to lead his followers to “martyrdom”, and the Shah did not have the stomach for mass bloodshed. This time the religious zealots are the ones holding power.The anger and the rage and sense of injustice people feel will not subside anytime soon, but if Mousavi concedes defeat he will demoralize millions of people. At the moment the demonstrations really have no other leadership. It’s become a symbiotic relationship, Mousavi feeds off people’s support, and the popular support allows Mousavi the political capital to remain defiant. So Mousavi truly has some agonizing decisions to make.
