Bahrain is a longtime ally that is pivotal to maintaining Persian Gulf security. Kuwait remains pivotal to U.S. efforts to secure the Persian Gulf region because of its consistent cooperation with U.S. strategy and operations in the region and its proximity to both Iran and Iraq. Qatar, a small peninsular country in the Persian Gulf, emerged as a partner of the United States in the mid-1990s and currently serves as host to major U.S. military facilities. The United Arab Emirates has been a significant U.S. partner in Gulf security for more than two decades, and the alliance has deepened further in recent years in order to address multiple regional threats. This book further discusses the U.S. relations with these four small countries of the Persian Gulf.
