After a seemingly never-ending will-they-won’t-they on the US-Iranian revival of the Iran nuclear deal, we seem to have an answer: they won’t.

As of today, officials from the United States, Europe, and Israel all say that the deal, also known as the Joint Comprehensive Plan of Action (JCPOA), is dead, at least for the foreseeable future. Reentering the deal was a major campaign promise of Joe Biden’s, it was something he didn’t need Congress to do, and it would have meant restoring one of the signature achievements of his Democratic predecessor, whose accomplishments Biden virtually treated as his own on the campaign trail. So how did it fail?

Hopes for renewing the agreement were, at first, raised after Tehran in August dropped its opposition to what seemed like the last sticking point in US-Iranian talks, namely the Iranian Revolutionary Guard Corps’s (IRGC) terrorist designation. That had been a poison pill deliberately issued by Donald Trump to complicate the deal’s revival, making Iran’s compromise on the matter significant.
