Former U.S. President Donald Trump is reportedly considering a highly provocative military action: ordering American troops to seize or blockade Iran's Kharg Island, a move that experts warn could cause "irrevocable damage" to the global economy. Multiple sources indicated the White House has discussed plans to occupy or blockade this crucial island, which serves as Tehran's most important economic asset and the launch point for approximately 90 percent of its oil exports. This consideration comes amid a broader escalation of conflict in the Middle East, with the U.S. having already deployed 5,000 Marines and sailors, alongside the amphibious assault ship USS Tripoli, to the region, signaling a potential ground operation.

Kharg Island, located 20 miles off Iran’s southern coast, is the undisputed heart of the nation's oil industry. Its 'Oil Boulevard' once boasted a loading capacity of roughly seven million barrels per day, making it a vital organ for Iran's sanction-hit economy. The primary goal of seizing the island would be to destroy the Iranian government's oil revenues or to use its control as a bargaining chip, compelling the regime to reopen the critical Strait of Hormuz. This strait is a chokepoint through which 20 percent of the world's oil and liquefied natural gas flows. White House adviser Jarrod Agen previously asserted that seizing Kharg Island would free the U.S. from concerns about Iran shutting down the Strait, effectively taking Iran's oil out of the hands of what he termed "terrorists."

However, the implications of such an action are dire. Retired Gen. Frank McKenzie, former commander of US Central Command, explicitly warned that destroying Iran's oil infrastructure would inflict "irrevocable damage to the Iranian economy and the global economy." Military action against Kharg Island poses an enormous risk of igniting a full-scale war across the Persian Gulf, potentially involving attacks on energy infrastructure, which could send crude prices surging and push the globe dangerously close to a recession. Oil prices have already shown significant volatility, with Brent futures rising to $109.85 a barrel and US West Texas Intermediate (WTI) crude hitting $96.20 following heightened tensions and the de facto closure of the Strait of Hormuz for much of the world's tanker traffic.

Donald Trump has repeatedly threatened to strike Iran's oil pipelines, asserting that such an operation could be executed on "five minutes' notice" and would take Iran "forever to rebuild." Yet, a ground operation to take over Kharg Island would be perilous for American troops, placing them directly in the line of fire. Experts suggest such a mission would likely need to follow extensive U.S. efforts to degrade Tehran's military capacity around the Strait of Hormuz, potentially requiring a month of strikes to weaken Iranian defenses before a ground assault. The White House and Pentagon are also reportedly considering sending even more soldiers to the region.

There are two main tactical approaches for seizing the island: by sea, using the USS Tripoli to launch ship-to-shore vessels carrying Marines and equipment; or by air, deploying Marines aboard F-35Bs and helicopters designed for runway-independent landings, launched from ships or nearby Gulf countries. Crucially, placing Marines on islands off Iran's coast, rather than on the Iranian mainland, could serve as a loophole, allowing a U.S. President to claim adherence to a promise of avoiding American boots on the ground in Iran proper. However, U.S. officials have acknowledged the immense risks, noting Iran's capability to target the island with drones and missiles.

The broader Middle East has seen a significant escalation in hostilities. Iran's military has issued severe threats to "hunt down" U.S. and Israeli officials and commanders globally, declaring tourist centers unsafe. Recent events include an Iranian drone attack on a Kuwaiti refinery, U.S. and Israeli strikes on 16 Iranian cargo vessels, heavy explosions in Dubai from intercepted rockets, and an Israeli attack on Syrian government positions. Israel also bombed Iran’s massive South Pars offshore natural gas field, prompting Iran to launch over a dozen missile salvoes at Israel. These attacks highlight the volatile nature of the conflict and have led to soaring oil and gas prices, alongside warnings of a spreading global economic shock exacerbated by what has been described as incoherent messaging from Washington.

Despite the grave risks, some strategists, like Michael Rubin, a former Pentagon official, view seizing Kharg Island as a "no-brainer" for choking off Tehran’s military funding. However, he cautioned that such attacks could embolden Iran’s hard-liners, complicating future diplomatic efforts. Oil analyst Tamas Varga likened such a move to the U.S. intervention in Venezuela's oil sector and warned of intensified conflict and vulnerability for U.S. forces. Petras Katinas, a research fellow, suggested that seizure would provide the U.S. with leverage in future negotiations, regardless of the post-conflict regime. Meanwhile, Rear Admiral (Ret.) Mark Montgomery proposed an alternative: two more weeks of attacks to degrade Iran's capabilities, followed by U.S. destroyers and aircraft escorting tankers through the Strait of Hormuz, potentially negating the need for an invasion. The contradictions in policy and the daily shifts in reported plans underscore the unpredictable and rapidly evolving nature of the conflict, with severe consequences for regional stability and global markets.
