The swarm of journalists killing time in the lobby of Geneva’s Intercontinental Hotel can finally go home. A deal has been reached between Iran and the P5+1 (Germany and the five permanent members of the UN Security Council, including the United States) in the ongoing dispute over the Iranian nuclear program. It’s not a final deal--all sides say they want something more comprehensive--and it’s only set to last six months. Yet it’s a remarkable step forward. The Iranian nuclear issue had smoldered for a decade. The diplomatic process appeared useless, if not dead. Only three things changed: Iran enriched more uranium, the world imposed more sanctions, and the risk of war grew. The new deal stands in the way of all three, but its value is broader. American and Iranian diplomats were meeting openly, and were apparently able to hammer out their differences on an important issue. A little more trust between the two states could yield benefits elsewhere. And the deal itself isn’t so bad, at least according to details released by the White House.
