One thing I know Trump will not do is send ground troops into Iran - I would back him if he wanted to seize and hold Kharg Island, though. THAT would DEFINITELY be a "forever war."
If the United States takes Kharg Island, how hard would it be to defend?

Very hard to defend long-term, despite being relatively straightforward to seize initially. Kharg Island (also spelled Kharg or Khark) is a small coral/limestone outcrop in the northern Persian Gulf, roughly 25–30 km (15–19 miles) off Iran's mainland coast near Bushehr. It measures about 8 km long by 4–5 km wide (~20 km² or ~8 sq miles), with low elevation (max ~70–87 meters). It hosts massive oil infrastructure handling ~90% of Iran's crude exports (up to ~7 million barrels/day capacity, ~30 million barrels storage), plus an airport, jetties for supertankers, and military sites.
Seizing It Would Be Feasible for the US
The US military could likely capture it with a brigade-sized or smaller force (estimates around 1,200–4,000 troops, e.g., a reinforced Marine battalion landing team or airborne elements from the 82nd, supported by MEUs with Ospreys, helicopters, and naval gunfire/air support).
- Methods: Airborne/air assault (helicopters/Ospreys) or amphibious landing after suppressing defenses. Prior air/naval strikes would neutralize Iranian SAMs, radars, missile boats, and bunkers. The island's small size and flat/ industrial terrain favor rapid seizure of key points (terminals, airport).
- Historical precedent: It was bombed repeatedly in the Iran-Iraq War and saw US strikes on military targets in 2026 (oil facilities often spared for leverage).
Iran's on-island forces (IRGC Navy elements, fast boats, some coastal missiles/drones) are limited and vulnerable to US air/electronic warfare superiority.
Defending It Would Be Extremely Difficult
This is the core challenge. Kharg sits too close to the mainland (~25 km), putting it in easy range of Iranian fires from the coast and interior. Key problems include:
- Proximity and Fire Support: Iranian artillery, rockets, ballistic/cruise missiles, drones (including FPV swarms), and anti-ship missiles could strike from the mainland continuously. Coastal batteries, mobile launchers, and mines add layers. The island offers little natural cover or depth—it's densely packed with oil tanks/pipelines (risk of massive fires/explosions) and low-lying.
- Asymmetric Threats: Reinforced defenses include MANPADS, anti-personnel/anti-armor mines on beaches/approaches, trenches, bunkers, and drone kill zones. Sustained resupply (ammo, fuel, water, food) via vulnerable sea/air routes would face ongoing harassment.
- Air/Sea Superiority Required Indefinitely: US forces would need persistent air cover, naval escorts (carriers, destroyers, Aegis for missile defense), Patriot/THAAD batteries on the island, minesweeping, and ISR. Iran could use cheap drones, mines, and speedboats to impose costs. Holding it turns into a siege where the defender (US) is on exposed, restricted terrain.
- Logistics and Attrition: Limited space for a large garrison or heavy equipment. Casualties could mount from rockets/drones even with superior tech. Political/domestic costs rise with sustained losses. Analysts compare it to historical island sieges (e.g., vulnerable positions under constant shore fire).
US experts note that taking it is doable but holding it risks turning into a costly, open-ended commitment—potentially a "suicide mission" in terms of attrition if Iran prioritizes harassment over protecting its own infrastructure. Strategic Context
- Value: High as a bargaining chip (control Iran's main oil revenue without total destruction) but limited for broader Gulf control (far from Strait of Hormuz, ~660 km / 410 miles northwest).
- Iranian Response: Tehran would likely escalate with proxies, mining, or strikes on Gulf shipping/US bases. They’ve already reinforced it with troops, mines, and MANPADS in response to threats.
- Alternatives: Blockade/enforcement (sinking approaching tankers) or strikes could disrupt exports with less risk than occupation.
Bottom line: The US could seize Kharg relatively quickly with acceptable initial losses under favorable conditions (air/sea dominance). Defending it against a motivated, nearby Iran would be a grinding, high-casualty nightmare requiring massive sustained resources—more like a liability than an asset unless it forces a quick political resolution. Real-world outcomes would depend heavily on the broader war context, escalation thresholds, and political will.
