The United States and Israel have conducted over 2,000 combat sorties against Iranian targets in the first 24 hours of operations, eliminating the Ayatollah and senior Revolutionary Guard leadership while targeting Iran's retaliatory strike capabilities. Iran's national security adviser is now in line to assume interim leadership as Iranian forces threaten retaliation using their remaining ballistic missile and drone capabilities. The conflict poses threats to approximately 40,000 US personnel in the region and Gulf Arab partner nations including Saudi Arabia, United Arab Emirates, Kuwait, Bahrain and Oman.
