Saudi-Iranian detente is fragile but potential for the Middle East is huge

Should rapprochement solidify it could augur well for Yemen, Lebanon and Syria - and spell disaster for Israel

Tehran's embassy in Riyadh has reopened for the first time since 2016, the Iranian foreign ministry quietly confirmed in April, in the latest of a series of gestures showing that the two Middle East powers are determined to dial down a rivalry that has disfigured the region for 40 years.

All kinds of signs, trivial and large, suggest the rapprochement is genuine: civilian flights between the two countries are to resume; an Iranian won an $800,000 Saudi Qur'an-reading competition; Iranian steel is making its way to Saudi markets; officials from the two countries were seen embracing after the Saudi navy rescued 60 Iranians trapped in Sudan; and Ibrahim Raisi is expected to announce a visit to Riyadh soon, the first by an Iranian president since 2007.
