History

The July 14 2015 Joint Comprehensive Plan of Action, signed by Iran and the P5+1 in Vienna, lifted sanctions and limited enrichment to several thousand centrifuges, freeing tens of billions of dollars in oil revenue. The deal built on the 2013 Geneva interim pact and the 2002 discovery of undeclared facilities, shaping today’s Tehran visit and calls for a new Gulf shipping plan.
