Iran is marking 40 years since the Revolution. Tehran this Monday is packed with people joining the crowd. Many of the banners pay tribute to Ayatollah Khomenei, who became the icon of the Revolution, and a hate figure for the West. The Shah was overthrown in 1979 after clerics turned against him and inflamed the youth who, just like today, needed jobs. So what do Iranians think of the last 40 years? Are they satisfied with the current situation?
