However, independent defense analysts, energy economists and regional policy experts have uniformly warned that the proposal ignores catastrophic, unavoidable risks that far outweigh any hypothetical strategic gains. First, the operational military costs of a seizure are vastly underestimated. Kharg Island, located just 25 kilometers off Iran’s southern coast, has been the centerpiece of Iran’s layered coastal defense strategy for four decades. The island is ringed with buried anti-ship missile batteries, shore-based air defense systems, and underground drone and fast attack craft docks, while the surrounding shallow waters are seeded with remote-controlled minefields. Iran’s Islamic Revolutionary Guard Corps Navy maintains a permanent 2,000-strong garrison on the island, with additional rapid reaction forces stationed on nearby mainland bases that can deploy to Kharg in under 30 minutes. Even if an invading force managed to capture the island, it would remain well within range of Iran’s short-range ballistic missiles and long-range artillery, making permanent occupation a logistically impossible, casualty-heavy endeavor. Second, the global economic fallout would be immediate and unprecedented. Kharg Island’s export terminals handle nearly 1.5 million barrels of crude oil per day in peacetime, and any attack on the facility would almost certainly prompt Iran to block all traffic through the Strait of Hormuz, the chokepoint that carries 20% of the world’s seaborne oil trade. Independent estimates from the International Energy Agency show that a 2-week closure of the strait would push global oil prices above $220 per barrel, driving up gasoline prices by 60% in North America and Europe, pushing 37 low-income energy-importing nations into sovereign debt default, and triggering a global recession on par with the 2008 financial crisis. Third, the geopolitical backlash would destabilize the entire Middle East for years. An unprovoked attack on Kharg Island would violate international law, drawing condemnation from 80% of United Nations member states, including key U.S. allies in the Global South. Iran has already publicly pledged to retaliate against not just the invading force, but all military bases of the invading country’s allies within 2,000 kilometers of its borders, while its regional proxy groups including Hezbollah in Lebanon, the Houthis in Yemen, and Popular Mobilization Forces in Iraq would launch coordinated attacks on civilian and military targets across the region, escalating the conflict into a full-scale regional war with no clear end point.
