Minefields, missiles, and Marines: The near-impossibility of cracking Hormuz

While the US and Israel maintain air superiority, their targets are dwindling, and their efforts are hampered by Iran's resilient defenses

The US-Israeli assault on Iran, now grinding into its third week, has ground to a tense halt, with Iranian ballistic missiles, cruise missiles, and drones giving Tehran a surprising edge. They are striking precisely at neighbouring Muslim states hosting US defence installations, turning the battlefield into a web of calculated retaliation that exploits regional fault lines. Meanwhile, America and Israel cling to air superiority, pounding a dwindling roster of viable targets just to keep the media narrative alive, but their bombs echo hollow against Iran's resilient defences.

US Navy ships, wary of Iran's missile swarms, hunker at a safe distance, slashing their time-on-task over Iranian skies and leaving carrier ops hamstrung. Attrition tilts Iran's way, and President Donald Trump hasn't articulated clear aims, or any at all, leaving Washington adrift in a quagmire. Withdrawal spells humiliation, especially with the Strait of Hormuz choked shut, a chokepoint for global oil that Iran vows to keep sealed. Stalemate suits Tehran perfectly; after nearly five decades of sanctions and a second brutal attack in under a year, survival itself is victory for a nation fighting existential dread.

Amid sideshows like Trump's pleas for NATO to muscle open Hormuz and Israel's claim of snuffing key Iranian leaders, a quieter drama unfolds: some 2,500 US Marines aboard the amphibious warship USS Tripoli have slipped from Okinawa, threading the Strait of Malacca toward the war zone, joined by another 2,500 from undisclosed spots, for a total of 5,000 leathernecks primed for action. As the Marine Corps' elite fourth service, they are masters of amphibious raids, island seizures, embassy guards, and hit-and-run-withdrawal strikes, backed by helos and air cover. But storming shores to crack the Strait, encircled by Iran from nearly three sides, courts slaughter, with mined approaches turning every passage into a deathtrap.

Demining the Strait verges on the near-impossible without dedicated wherewithal: no possible allies or the US minesweepers, US Littoral Combat Ships with MCM packages are scarce, and leftover minesweeping helos, if any, would fly into MANPADS hell. Recent US bombers have hammered Iran's Hormuz-facing coastline with 5,000-pounders, targeting coastal batteries and cruise pads, but hilly terrain and deep-dug Iranians shrug it off. Eyes lock on five islands guarding the mouth, Qeshm (the Gulf's behemoth), Hormuz, Larak, Hengam, and Abu Musa or Kharg Island, softened but pumping 90 per cent of Iran's oil to fund China. Marines charging any would face missile barrages, gun batteries, and minefields, with carriers too distant for full air cover, UAE/Saudi / other airbases wobbly, and USNS Tripoli a nice fat target. Heli-drops? Exposed. Destroyers? Fair game. Helicopters battling MANPADS, It's a butcher's yard.

Kharg Island, the hub of Iran’s oil exports, tempts some planners as an economic blow, but it remains a dangerous gamble that could destabilise neighbouring countries' oil economies. Even more extreme ideas, such as seizing Iran’s uranium stockpiles, are being discussed, though I believe this would be a nightmare mission for even the most elite forces. Meanwhile, casualties are already rising , 13 Americans killed and about 200 wounded, testing Trump’s promises to avoid new wars. Yet he continues to talk about “boots on the ground,” while allies remain reluctant to commit.

The White House insists no ground assault is imminent, but Trump keeps his options open under Operation Epic Fury, which aims to destroy Iran’s missile forces, cripple its navy, weaken its proxies, and prevent it from acquiring nuclear weapons. The campaign has already suffered setbacks, with the USS Gerald R. Ford forced into repairs in Greece after a fire, reducing available airpower. Losses mount even without US forces setting foot on Iranian soil. Looking ahead, the nuclear question looms large. Iran’s fissile material is beyond America’s reach, and any escalation risks mutual destruction. The Marines threatened deployment may be more about posturing than fighting, buying time and signalling resolve rather than preparing for a bloody landing. The Strait of Hormuz remains closed, and any attempt to storm it would mean sunk ships and heavy casualties. Without the ability to clear mines, Iran’s encirclement holds. Trump may ultimately seek a way to freeze the conflict while saving face, relying on proxies and avoiding a forever war. But if the US cannot overpower Iran, Tehran is likely to emerge stronger, and potentially nuclear-armed, for its existence, before Trump’s term ends.
