The final agreement is based on (and supporting) “the rules-based non-proliferation regime established by the Non-Proliferation Treaty (NPT), including, in particular, the IAEA protection system.”  The United Against Nuclear Iran (UANI) group rejected the agreement and committed to spend more than $20 million on a “national television, radio, print and digital campaign” against the agreement.   After UANI announced its opposition, the group`s president and co-founder, non-proliferation expert Gary Samore, announced that he had concluded “in the interest of the United States” and supported the agreement.

The letter was coordinated by a group of Quakers, the Friends Committee on National Legislation.  Among the signatories of this letter was Jim Wallis of Sojourners; John C.
