After a long hiatus, the Godot of US-Iran diplomacy may finally arrive in 2013, in light of the reciprocal overture at the recent Munich Security Conference, featuring the signs of a new approach to Iran articulated by Vice President Joe Biden. Iran's foreign minister,Ali Akbar Salehi, who also attended the conference, welcomed Biden's call for "serious dialogue" between the two countries and urged Washington to show its good will toward Iran. And although Iran's spiritual leader has questioned the wisdom of bilateral talks with the United States as long as it is "pointing a gun," Iran has nonetheless moved the chess pieces forward by agreeing to the next round of multilateral talks with the UN Security Council's five permanent members plus Germany (or P5 + 1), which begin in Kazakhstan this week.
