Kerry's meeting with Saudi Foreign Minister Adel al-Jubeir (AD'-duhl ahl-joo-BEHR') comes amid America's own difficulties with the Sunni kingdom, and as Shiite Iran looks forward to a huge payoff in sanctions relief for implementing the nuclear deal.
Saudi Arabia is wary of that scenario. Washington opposes the mass executions Saudi Arabia carried out Jan. 2, sparking the crisis with Iran, which led to Saudi Arabia and others cutting diplomatic ties.
Kerry said in London today that countries in the region shouldn't interfere in others' affairs. But he said he wants diplomacy to work.
