The Trump administration is confronting mounting discontent from allies in the Persian Gulf who have complained they were not given adequate time to prepare for the torrent of Iranian drones and missiles bombarding their countries in retaliation for strikes launched by the U.S. and Israel.

Officials from two Gulf countries said their governments were disappointed in the way the U.S. has handled the war, particularly the initial attack on Iran last Saturday. They said their countries were not given advance notice of the U.S.-Israeli attack and complained the U.S. had ignored their warnings that the war would have devastating consequences for the entire region.
