The Iranian revolution has completed two decades. In some ways it has changed; in other ways not. At this moment, an interesting contest seems underway. Will moderate political forces hold sway or will conservative clerics insist on the fundamentalist parity of their society. Key sectors of the population are the target and the prize of these rival forces. Youth are restive and women are somewhat frustrated. The middle class and its institutions are the ultimate arbiters of Iran's future. Journalist Elaine Sciolino explains what is at stake.
