"The United Arab Emirates (UAE) is a significant U.S. partner in Gulf security, helping to address multiple regional threats, particularly that posed by Iran. About 5,000 U.S. military personnel are stationed at UAE military facilities, hosted there under a bilateral defense cooperation agreement (DCA) that remains in effect. The UAE is a significant buyer of U.S. military equipment, including sophisticated missile defenses, and it reportedly wants to buy the F-35 combat aircraft. The alliance is expected to continue after UAE President Shaykh Khalifa bin Zayid Al Nuhayyan, who suffered an incapacitating stroke in January 2014, leaves the scene and his younger brother, Shaykh Muhammad bin Zayid, inevitably assumes formal power as UAE president."
