President Trump welcomed Kuwaiti Emir Sabah al-Ahmad al-Jaber al-Sabah to the White House Thursday, saying he was prepared to help mediate a dispute the Gulf kingdom and its allies have with Qatar—which Trump has accused of supporting terrorism. President Trump also praised Kuwait’s monarch for purchasing U.S.-made weapons, including warplanes.

President Donald Trump: “Kuwait has purchased a tremendous amount of military equipment and other equipment—many 777s from Boeing, a lot of F-18s from us. We’re going to be talking about additional orders and military orders.”

Kuwait is a member of the Saudi-led military coalition that’s been bombing Yemen since March of 2015. This week, the U.N. said the airstrikes were responsible for most of the 1,100 killed during the war, calling the ongoing famine and cholera epidemic in Yemen an “entirely man-made catastrophe.”
