From the Summary: "The Sultanate of Oman has been a strategic partner of the United States since 1980, when it became the first Persian Gulf state to sign a formal accord permitting the U.S. military to use its facilities. Oman has hosted U.S. forces during every U.S. military operation in the region since then, and it is a partner in U.S. efforts to counter terrorist groups and other regional threats. In January 2020, Oman's long-time leader, Sultan Qaboos bin Sa'id Al Said, passed away and was succeeded by Haythim bin Tariq Al Said, a cousin selected by Oman's royal family immediately upon Qaboos's death. Sultan Haythim espouses policies similar to those of Qaboos and has not altered U.S.-Oman ties or Oman's regional policies."
