Iran Threatens Nuclear Treaty Exit as Europe Weighs Sanctions 'Snapback'

Iran is warning it may withdraw from the Nuclear Non-Proliferation Treaty (NPT) if Britain, France, and Germany (the E3) move to reimpose UN sanctions over its nuclear program.

The threat comes as the E3 consider triggering the 'snapback' mechanism, which would restore international sanctions lifted under the 2015 nuclear deal, citing Iran's breaches of the agreement. In response, Iran is seeking support from Russia and China to counter Western pressure and is set to hold urgent talks with the E3 in Istanbul. The diplomatic standoff has heightened tensions, with Iran also threatening to reduce regional security cooperation if sanctions return.

The coming weeks are seen as critical for the future of the nuclear deal and regional stability.
