Analysis of the U.S. Response to the Incident Where a Merchant Vessel Was Attacked in the Strait of Hormuz
The U.S. carried out airstrikes on missile and drone storage sites and coastal radar in southern Iran, citing the reason that U.S. forces were responding to an unmanned drone attack on a Singapore-flagged merchant vessel in the Strait of Hormuz. This is the first time the U.S. has taken the initiative to strike targets on its own soil since the U.S. and Iran reached a temporary understanding memorandum. On the surface, it is retaliation for the attack on shipping; at a deeper level, it reflects multiple demands, including deterrence, control of shipping routes, and broader geopolitical maneuvering.
1. The U.S.’s superficial demands: safeguard freedom of navigation and deliver deterrence
The Strait of Hormuz is a key global energy shipping chokepoint. Under the banner of “ensuring freedom of navigation,” the United States has taken military action and sent signals to shipping nations and Gulf allies: the U.S. will respond with force to an attack on merchant vessels in the strait, thereby strengthening its own authority over maritime security discourse. At the same time, it accuses Iran of violating the ceasefire understanding, drawing a red line by means of military strikes, suppressing Iran’s freedom of maritime action in the strait, and preventing attacks on vessels from becoming routine disruptions to global shipping and oil prices. The chosen strike targets include military support facilities such as weapon depots and radar, rather than cities or nuclear facilities. The U.S. is deliberately limiting the intensity of strikes, aiming to punish rather than launch a full-scale war.
2. Underlying strategic intentions
1. Consolidate Middle East alliances: By conducting escort operations, the U.S. seeks to maintain Gulf states’ trust in American security commitments, strengthen the U.S. military presence in the Persian Gulf, and prevent GCC countries from independently easing relations with Iran.
2. Bargaining and leverage: The U.S. and Iran are both within a window for temporary ceasefire talks. The U.S. airstrikes are not only punishment for the vessel attack, but also a way to raise the bargaining terms through military pressure, pushing Iran to make concessions on issues such as navigation and oil exports.
3. Shaping external positioning: By framing the narrative as “anti-attack and protection of shipping,” the U.S. aims to secure public opinion and gain a neutral stance from shipping countries, attributing the cause of the conflict to Iran and avoiding international pressure that would otherwise increase demands for an offensive full-scale war.
3. Directions of risk in the evolving situation
Iran views the U.S. cross-border strikes as an infringement on sovereignty and will likely respond in a tiered manner: small-scale drone attacks, maritime warning and counterattacks, and regional pressure via proxies, rather than immediately launching large-scale cross-border airstrikes. Both sides are expected to continue their “limited confrontation, avoiding full-scale war” bargaining. In the short term, the risk to navigation through the strait is likely to rise, and international oil prices and shipping insurance rates may fluctuate. If the temporary ceasefire agreement develops cracks, the pattern of border frictions between the U.S. and Iran followed by continued talks will persist, and the probability of heightened, ongoing tension becoming normalized in parts of the Middle East will increase.
