Iran has recently bolstered its defenses around Kharg Island, anticipating a possible US move to seize the key oil export hub, CNN reported this week. The island is vital to Iran’s economy, handling roughly 90% of its crude shipments, and has become a focal point in escalating tensions.

The Trump administration has explored the option of sending US forces to take control of the island as leverage to pressure Iran into reopening the Strait of Hormuz. But military officials caution that such an operation would carry serious risks. Iran has reinforced the island with additional air defense systems, including portable missiles, and has planted mines along likely landing zones.

There is also growing skepticism among US allies and policymakers about whether capturing the island would achieve its broader objective. Even if successful, it may not resolve the wider dispute over energy flows and could instead intensify the conflict. An Israeli source warned that US troops could face attacks from drones and shoulder-fired missiles if they attempt a landing.

“I would be very worried about this,” said retired Adm. James Stavridis. “Iranians are clever and ruthless. They will do everything they can to inflict maximum casualties on US forces both on the ships at sea, and especially once ground troops are anywhere in their sovereign territory.”

CNN writes that Iran has responded with its own warnings. Parliament speaker Mohammad Bagher Ghalibaf said any attempt to occupy Iranian territory would prompt retaliation against critical infrastructure in the region, adding that US troop movements are under close watch.

Despite its relatively small size—about one-third of Manhattan—Kharg Island would require a substantial military operation to capture. US forces in the region include Marine units trained for amphibious assaults, along with airborne troops preparing to deploy. Surveillance has shown newly fortified positions and defensive preparations on the island.

Although earlier US strikes weakened parts of Iran’s defenses, American forces would still face significant threats from missiles and drones launched from the nearby mainland. This has led to internal debate in Washington over whether the potential benefits justify the risks.

Regional allies are urging restraint, warning that a ground assault could result in heavy casualties and trigger wider retaliation across the Gulf. Some analysts suggest that targeting Iran’s oil exports through a naval blockade could be a less risky alternative to putting troops on the ground.
