A new report from the Congressional Research Service begins to sort through the implications and the practical consequences of the Trump Administration decision to end US compliance with the Iran nuclear agreement, known as the Joint Comprehensive Plan of Action (JCPOA).

“The Trump Administration could have used provisions of the JCPOA itself to cease implementation of U.S. commitments under the agreement. It opted not to do so, but instead to cease implementing the JCPOA by reimposing U.S. sanctions,” the CRS report noted.

See U.S. Decision to Cease Implementing the Iran Nuclear Agreement, May 9, 2018.

For related background from CRS, see also Iran: U.S. Economic Sanctions and the Authority to Lift Restrictions, updated May 10, 2018; Withdrawal from International Agreements: Legal Framework, the Paris Agreement, and the Iran Nuclear Agreement, updated May 4, 2018; and Iran Nuclear Agreement, updated May 2, 2018.

The decision to unilaterally reimpose sanctions on Iran took the form of a National Security Presidential Memorandum (NSPM) on May 8. Although the NSPM posted on the White House website is unnumbered, the copy circulated to reporters was identified as NSPM-11.

It follows that the previous NSPM on conventional arms transfers, which was also unnumbered on the White House website, must have been NSPM 10.
