“Frustration with Washington is growing in the Persian Gulf region, where U.S. allies are increasingly concerned that President Donald Trump is unable to manage the diplomacy necessary to secure peace with Iran, Arab and Western officials say,” the Washington Post reports.“Trump in recent weeks has repeatedly issued threats against Iran, only to withdraw them, citing progress in talks. After months of conflict, and continuing missile and drone strikes by Iran and its proxies, the governments of Saudi Arabia, the United Arab Emirates, Qatar, Kuwait and Bahrain are now united in their aggravation with the administration. Some have begun to debate the utility of continuing to host large U.S. military installations on their territory.”
