United States National Security Advisor John Bolton and United Arab Emirates National Security Advisor Sheikh Tahnoon bin Zayed Al Nahyan are pleased to announce the entry into force of the Defense Cooperation Agreement (DCA) between the United States and the United Arab Emirates.  The DCA will enhance military coordination between the United States and the United Arab Emirates, further advancing an already robust military, political, and economic partnership at a critical time. The United States and the United Arab Emirates share a deep interest in promoting prosperity and stability in the region.  The DCA will advance that interest by fostering closer collaboration on defense and security matters and supporting efforts by both nations to maintain security in the Gulf region.
