US Officials Suffering Inability to Understand Int'l Law , UN Structure

"After thrice being rejected by SC, US now threatens sanctioning anyone & any entity that comes between US and its snapback. Obviously they don't understand law or UN," Zarif wrote on his Twitter account on Friday.

"Maybe they can grasp this: You divorced the JCPOA in 2018. Your name on the marriage certificate is irrelevant," he added.

In a relevant development earlier this week, Zarif in a letter to the chairman of the UN Security Council blasted the US' illegal attempts to snapback sanctions on Iran, reiterating that the US has no right to reapply provisions of terminated resolutions.

The Iranian foreign minister said that the term “snapback” is never employed in either the Joint Comprehensive Plan of Action (JCPOA) or UN Security Council Resolution 2231, rather, the US has intentionally used the term to connote rapidity and automaticity.

"The wording in UNSCR 2231 is actually “reapplication of the provisions of terminated resolutions”, which requires an elaborate time-consuming process intended to preserve the JCPOA, and not to destroy it," he added.
