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 alleged non-compliance. In response, Iran is seeking diplomatic support from Russia and China to counter Western pressure and is set to hold urgent talks with the E3 in Istanbul. The outcome of these negotiations could determine whether Iran faces renewed isolation or a path back to diplomacy.

The situation is tense, with both sides warning of serious consequences if no agreement is reached.
