On Monday, we learned that the Iranian regime was behind a plot to kill the Saudi ambassador to the U.S. in this country. We also discovered that Iran was looking for help within the Mexican drug cartels to carry out this and future plots against targets in the western hemisphere. So how can we be sure this plot went all the way to the top in Iran? What does this tell us about Iran’s confidence right now? And what should be the U.S. response? We ask Alireza Jafarzadeh, former spokesman for the Iranian Parliament in Exile and the man who warned the West about Iran’s latest nuclear intentions.
