The Middle East policy of US President Donald Trump's administration appears to be a work in progress, with some parts shaped by events and others a continuation of his first administration. The US has increased sanctions against Iran and designated the Houthis as a foreign terrorist organization. The administration has refrained from commenting on Israeli attacks in Gaza and has accelerated deliveries of weapons used in those attacks. US regional partners need to fill significant gaps in policy. Trump's upcoming visit to Saudi Arabia will raise expectations about America's regional role.
