What Happened
- Iran launched retaliatory missile and drone strikes on US military bases across multiple Middle Eastern countries on 28 February 2026, following US-Israeli joint strikes on Iranian territory
- The Islamic Revolutionary Guard Corps (IRGC) claimed it targeted 27 bases hosting US troops, as well as Israeli military facilities
- Key targets included Al Udeid Air Base (Qatar), Al Dhafra Air Base (UAE), the US Fifth Fleet headquarters in Bahrain, and Al-Salem Air Base in Kuwait
- Saudi Arabia, Iraq (including Erbil Airport in the Kurdish region), Jordan, and British military bases in Cyprus were also targeted
- The operation was named "True Promise 4" by Iran; most strikes were intercepted by regional air defence systems

US Military Presence in the Middle East and CENTCOM
The United States Central Command (CENTCOM) oversees all US military operations across a 21-country region stretching from Egypt to Central Asia. The Middle East hosts the most concentrated cluster of US forward-deployed forces outside of Europe and East Asia, with major facilities distributed across Gulf Cooperation Council (GCC) states.
- Al Udeid Air Base (Qatar): Largest US base in the Middle East, forward headquarters of CENTCOM; approximately 10,000 troops; serves as the primary air hub for operations in Iraq, Afghanistan, and Syria
- Al Dhafra Air Base (UAE): Located 30 km south of Abu Dhabi; hosts the US Air Force 380th Air Expeditionary Wing; approximately 1,200 personnel; operational since 2002
- Naval Support Activity Bahrain: Home of the US Fifth Fleet, responsible for naval operations in the Persian Gulf, Red Sea, and parts of the Indian Ocean
- Al-Salem Air Base (Kuwait): Key logistics and air operations hub used during Gulf War operations
- These bases have been critical to US power projection in the region since the 1991 Gulf War
Connection to this news: Iran's retaliatory strikes directly targeted this network of US forward bases, attempting to raise the cost of the US-Israeli operation by threatening American military infrastructure across multiple sovereign Arab states simultaneously.
Gulf Cooperation Council (GCC) — Formation, Membership, and Strategic Role
The Gulf Cooperation Council is a regional intergovernmental political and economic union of six Arab states of the Arabian Peninsula, established in 1981. Member states are Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates. The GCC was formed partly in response to the threat perceptions generated by the 1979 Iranian Revolution and the 1980 Iran-Iraq War.
- Founded: May 25, 1981, in Abu Dhabi
- Headquarters: Riyadh, Saudi Arabia
- Primary objectives: Coordination in economic, social, cultural, and security affairs; common market and customs union; collective defence
- GCC states host the bulk of US forward military presence in the Middle East under bilateral defence agreements (not a formal NATO-style collective defence treaty)
- The GCC established a Peninsula Shield Force for collective defence, though US bilateral security guarantees remain the primary security architecture
- Iran–GCC relations have been historically tense due to sectarian divisions (Sunni Arab states vs. Shia Iran), competition for regional hegemony, and Iran's nuclear programme
Connection to this news: Iran's strikes on Bahrain, Kuwait, Qatar, and UAE simultaneously targeted all of the major GCC states hosting US assets, representing a direct challenge to the US-GCC security architecture that has underpinned Gulf stability since 1991.
Iran's IRGC — Structure, Role, and "Axis of Resistance"
The Islamic Revolutionary Guard Corps (IRGC) is a branch of Iran's armed forces established after the 1979 Islamic Revolution, charged with protecting the clerical government's institutions. Distinct from the regular Iranian army (Artesh), the IRGC reports directly to the Supreme Leader and operates a parallel military structure including ground forces, navy, air force, and the Quds Force (external operations branch).
- Established: May 5, 1979, by decree of Ayatollah Khomeini
- The Quds Force is the IRGC's extraterritorial operations arm, responsible for supporting allied non-state groups (Hezbollah, Hamas, Houthi, Iraqi militias) — collectively termed Iran's "Axis of Resistance"
- US designated the IRGC as a Foreign Terrorist Organization in April 2019
- The IRGC operates the Shahab, Fateh, and Hypersonic Fattah ballistic and cruise missile systems
- "True Promise" operations: Iran launched Operation True Promise 1 (April 2024, direct strikes on Israel), True Promise 2 (October 2024), and the current True Promise 4 — marking a significant escalatory ladder
Connection to this news: The "True Promise 4" operation is the IRGC's most expansive direct-strike campaign, targeting US assets across seven countries simultaneously rather than focusing solely on Israel, representing a qualitative escalation in Iran's use of its ballistic missile arsenal.
Strategic Geography — Persian Gulf Chokepoints
The Persian Gulf and its surrounding waters contain some of the world's most strategically vital maritime chokepoints. The Strait of Hormuz, at the mouth of the Persian Gulf between Iran and Oman, is approximately 33 km wide at its narrowest and handles about 20% of global oil trade (roughly 17 million barrels per day).
- Strait of Hormuz: 33 km wide at narrowest point; 21 million barrels of oil per day pass through (pre-conflict estimates); Iran has repeatedly threatened to close it
- Strait of Hormuz is flanked by Iran on the north and the UAE (Musandam exclave of Oman) on the south
- The Persian Gulf is approximately 989 km long and 56–338 km wide
- GCC states (especially UAE and Qatar) depend on the Strait for oil exports; LNG exports from Qatar make up ~22% of global LNG trade through this corridor
- A conflict that escalates to include Hormuz closure would trigger a global energy crisis
Connection to this news: Iran's strikes on GCC airspace and air bases, combined with its existing capacity to threaten the Strait of Hormuz, underline why this conflict has immediate implications for global energy security and why GCC states face acute vulnerability even when they are not primary combatants.
