While having granted Europe a chance to save the Joint Comprehensive Plan of Action (JCPOA), Iran is in parallel mulling an exit from the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in response to the US withdrawal from the JCPOA. Such a move would be accompanied with many legal complications but is nonetheless among the most likely of Iranian responses should Europe fail to guarantee that its interests will be protected as outlined in the nuclear deal.
US President Donald Trump’s stepping up of his threats to pull out of the JCPOA in the months leading up to his May 8 withdrawal prompted Iranian officials to retort that the West — and especially the United States — would be surprised by their response were Trump to follow through with his threats.
