The following is the Feb. 9 2026, Congressional Research Service In Sight report, Iran’s Nuclear Program and UN Sanctions Reimposition. From the report UN Security Council Resolution 2231 (2015), which the council adopted on July 20, 2015, implements the Joint Comprehensive Plan of Action (JCPOA) and contains other provisions concerning Iran’s nuclear program, Tehran’s development of missiles, and arms transfers to and from Iran.
In August 2020, the United States invoked the resolution’s “snapback” mechanism, which requires the Security Council to reimpose UN sanctions lifted pursuant to Resolution 2231 and the JCPOA. (See CRS Report R40094, Iran’s Nuclear Program: Tehran’s Compliance with International Obligations, by Paul K. Kerr.) Although that effort failed, France, Germany, and the United Kingdom (UK) (collectively known as the “E3”) on August 28, 2025, invoked the snapback mechanism, which resulted in the sanctions’ reimposition on September 27, 2025.
