Last week, Iranians went to the polls, and reportedly elected moderates to represent them in their parliament, the Majlis.

But in Iran, nothing is quite as it seems. Moderates may not really be moderates, and bodies such as the Majlis have only limited power. The real power lies with the Supreme Leader.

Yet despite the impediments, there's one reason that the election may end up having an important effect later down the line.

Dr. Emily Landau, head of the Arms Control and Regional Security Program at the Institute for National Security Studies, discusses the election and its implications.
