Zachary Lockman, professor of Middle Eastern and Islamic Studies and History at New York University analyzes what he sees happening in Egypt, where throngs have descended on Tahrir Square following President Mubarak’s refusal to step down. It seemed that Vice President Omar Suleiman was going to take the place of President Mubarak, but it appears that he is lock step with Mubarak. Lockman says that the old political parties in Egypt have no credibility. He also expresses a wariness that if the regime tries to revive it’s security apparatus and use it against the demonstrators, an explosive situation will ensue.
