The United States' allies in the Middle East are standing by the White House, despite Iran's retaliatory attacks following the U.S. and Israel's killing of Iran's Ayatollah Ali Khamenei and top officials. Iran has targeted neighboring Gulf states, including Qatar, where the largest U.K. military base is located. Qatar has called for an immediate cessation of all escalatory actions and efforts to contain the crisis. Other American allies in this region have also been attacked, including Bahrain, Jordan, Kuwait, Saudi Arabia and the United Arab Emirates. The CIA headquarters in Riyadh was hit by a suspected Iranian drone, but no casualties were reported. Despite Iran's retaliation, the situation has escalated and questions grow about how much Gulf allies can take.
