SW Asia (Gulf) holds ~50% of world proven reserves. U.S. is top importer; stable flow at market prices is paramount. Military presence (CENTCOM, 5th Fleet) underwrites this.
Region spawns transnational threats (Al-Qaeda, ISIS, Iran proxies). U.S. conducts CT operations (Afghanistan, Iraq, Syria) and builds partner capacity.
Rhetorical commitment: support reformers, condemn abuses. Inconsistent application (allies vs. adversaries) draws criticism.
U.S. exports (defense, tech, ag), investment, and aid (USAID) aim to diversify economies beyond oil, create jobs, reduce instability drivers.
Interests often conflict (e.g., stability vs. democracy). Policy shifts by administration; core = energy security + threat prevention.
