Assessing the 10 March agreement between Iran and Saudi Arabia, a senior U.S. diplomat indicated that “the first order of business will be to see whether it reflects that Iran will live up to its commitments in terms of Yemen and that it will cease the kind of lethal aid and training that it has provided to a number of non-state actors, some of whom have attacked the kingdom in a constant way over the last few years... Anything that starts with the de-escalation of tensions between two big, significant actors in the region – Saudi Arabia and Iran – anything that provides an enduring kind of détente in the tensions and confrontation that they’ve had over the course of years is a great thing and should have wider regional effects”.
