75 experts from the Arms Control Association have come out today with a statement to endorse the P5+1 nuclear deal with Iran, saying the pact was a “net plus for nuclear nonproliferation” and exceeds historical standards on arms control limitations.

The signatories of the statement include several high-profile opponents of the 2003 US invasion of Iraq, including Joe Wilson and Valerie Plame, along with former IAEA chief Hans Blix and former US Ambassador Morty Halperin.

The statement goes on to echo the comments of other proponents, saying it will make it easy for the international community to detect any clandestine program by Iran, and will “decisively prevent Iran from acquiring a nuclear weapon.”

Congress is planning to vote on the deal on September 17, and is expected to have a majority against the deal. It is not, however, expected to get the veto-proof majority that would be needed to attempt to block US participation in the pact outright.
