Iran, China, and Russia jointly announced the termination of UN Security Council Resolution 2231 provisions after October 18, 2025. This action confirms the end of the UNSC's formal consideration of Iran’s nuclear issue, alongside confirming the expiration of IAEA verification duties under the 2015 JCPOA.

The dispute centers on who has the authority to revoke sanctions. Critics, citing joint letters, accuse the US of illegally and unilaterally withdrawing from the JCPOA in 2018. Furthermore, multiple sources argue the E3 nations forfeited their standing by failing to adhere to their own commitments under both the JCPOA and Resolution 2231, leading to their 'snapback' attempts being labeled 'illegal.' User rainpizza reinforced this, noting the E3's own lack of adherence, while Socialism_Is_The_Alternative provided the details on the sequencing of these formal terminations.

The prevailing narrative is that the US and E3 nations lack legitimate standing to enforce sanctions measures. The consensus points to a formal multilateral shutdown of the UNSC file, undermining previous sanctioning efforts by Western powers due to alleged treaty violations by the E3 themselves.
