The U.S. ambassador to the UN told the Security Council that “Iran is the single greatest threat to peace and security in the Middle East… We are confronting the full range of Iran’s destabilising activities, from its support of terrorist groups and proxies, to its development of ballistic missiles in defiance of the Security Council”. “This Council must simply muster the courage to hold Iran accountable to its existing international obligations. And it is a fact that Iran is neither abiding by the letter nor spirit of this Council’s decisions”, she added. “The U.S. will continue to hold Iran accountable, even if it means we must act alone… While we will continue our maximum pressure campaign to deny the regime the means to continue fueling terror, we stand ready to meet Iran at the negotiating table to conclude a comprehensive deal”.
