The debate over the future direction of the Green Movement has taken on new urgency since the events in Tehran on February 11, the 31st anniversary of the Iranian Revolution. The saturation of Tehran with tens of thousands of security forces and intelligence agents prevented supporters of the Movement, who according to many sources were present in very large numbers, from forming large groups and putting on a show of strength. The crackdown was violent: Anyone who exhibited any symbol of the Movement was arrested. Mehdi Karroubi and his son, Ali, were beaten. Former president Mohammad Khatami was attacked in his car. Many thousands of members of the Basij militia, as well as people from the town and villages around Tehran, were brought to attend Mahmoud Ahmadinejad’s speech in Azadi Square, from which the opposition was entirely blocked (see aerial photos of the event here and here).
