In China, Deng won. In Iran, "Deng" is certainly on the side of the protesters. For all the talk of an Iranian Tiananmen, the dynamic in Tehran is much closer ot 1976 (where the Communist government crushed demonstrators, and lost all legitimacy) than 1989.
The hope for pro-globalization reforms in Iran depends on the current government in Tehran losing its credibility and legitimacy. If Tehran will ever be as synonymous with growth and openness and Beijing, the Supreme Leader should face the same road as Madam Mao.
