It took President Joe Biden more than a month to schedule a phone call with King Salman of Saudi Arabia, a contrast to his predecessor Donald Trump, who chose the kingdom as his first foreign destination after the election. Even though Saudi Arabia is considered a key ally in a volatile region, Mr Biden took a tough stance on the kingdom during his campaign. He promised to end the sale of offensive weapons used in Saudi Arabia's war in Yemen, and accused its crown prince, Mohammed bin Salman, of directly ordering the killing of the journalist Jamal Khashoggi. Mr Biden also pledged to restart nuclear talks with Iran, and further reduce America's dependence on fossil fuels, putting Washington at odds with the political and economic priorities of Riyadh. Now, as his administration looks for a reset of relations, what are the friction points in the decade old alliance between the two countries? Will a push for recalibration encourage Saudi Arabia to seek out new alliances at the expense of the United States? And can US policies succeed in the region by antagonising one of the leading countries in the Muslim world? Join Ritula Shah is joined by a panel of experts.
