Executive Summary
The E3 (France, Germany, UK) invoked the snapback mechanism in August 2025, reimposing UN sanctions on Iran related to its nuclear program, despite prior US attempts failing. This action effectively ended the JCPOA and extended the Security Council's consideration of Iran's nuclear issue indefinitely. Recent US-Israeli airstrikes on Iranian nuclear facilities and a June 2026 MOU between the US and Iran further complicate the situation.
