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."
