Addressing a UN Security Council session on the thirteen biannual report on UNSC Resolution 2231’s implementation, the ​U.S. representative stated: Iran “continues to carry out activity related to ballistic missiles designed to be capable of delivering nuclear weapons in defiance of Annex B of Resolution 2231. Launches of space launch vehicles… relied on technology virtually identical to, and interchangeable with, those used in ballistic missiles designed to be capable of delivering nuclear weapons”. “The Security Council must be clear and united in condemning this activity. When Iran defies the Security Council repeatedly – without consequence – it undermines the fundamental credibility of this Council”, the U.S. diplomat emphasised. Addressing the same session, Iran’s UN envoy countered that “our space and missile programs, fall outside the purview or competence of the UNSC resolution 2231 and its annexes and are not subject for negotiations”.
