RM: Why is the Mujahideen-e-Khalq labeled a terrorist organization by the State Department and should it/will it remain that way?
GM: The Clinton Administration designated them a terrorist organization based on its murder of Americans and loyalties to at one time Khomeini, then later to Saddam. During the Iran/Iraq war the MEK fought and killed Iranians. As a result, inside of Iran they are almost universally considered traitors. I am not an expert in the MEK but I know that the Iranian people overwhelmingly hate the MEK and if the U.S. were to change their designation it would cause them to believe that the U.S. has made peace with their enemy. This would be a huge mistake.
