It’s one for the history books. For the first time in more than three decades, the Presidents of the United States and Iran have spoken on the telephone. After days of promising gestures toward resolving the dispute over Iran’s controversial nuclear program, the two sides came to this pivotal point: a 15-minute chat. After the call, Obama appeared hopeful, saying that despite inevitable obstacles, he ”believes we can reach a comprehensive solution.” President Rouhani returned to Tehran to a “chaotic” scene of both cheering supporters and shoe-throwing opponents chanting “Death to America.” Talks between Iran and the negotiating group P5+1 are just weeks away. Could this mean a possible end to economic sanctions on Iran and the beginnings of peace?
