On Foreign Entanglements, Matt and Meir discuss the Iran nuclear negotiations. They disagree over whether the Arak reactor should be halted as a first step or under a final deal, but agree that additional sanctions now being considered by Congress are a bad idea. Would a nuclear deal help or hinder the cause of political reform in Iran? Turning to Israel, Matt can’t believe that Avigdor Lieberman is now sounding more reasonable than Netanyahu. Does Bibi recognize the linkage between settlements and Iran?
