What Happened
- US President Trump publicly mused about seizing Kharg Island, Iran's main oil export terminal in the Persian Gulf, as a way to pressure Tehran and gain leverage in the ongoing conflict.
- On March 13, 2026, the US military conducted strikes that "totally obliterated" military infrastructure on Kharg Island, though oil and gas processing facilities were deliberately spared in that initial operation.
- Analysts have identified three core problems with a full seizure and occupation of Kharg Island: the military cost of holding it against Iranian counterattacks, the environmental catastrophe that could result from any damage to its oil infrastructure, and the risk that it would unite global opposition — including from allies — against the US.
- The discussion invokes an ominous legal and strategic precedent: the seizure of another state's sovereign economic infrastructure by military force would be the most significant such act since Iraq's occupation of Kuwait in 1990 and could undermine the rules-based international order.
- Even if seized, Kharg Island's utility is limited without trained Iranian operators, and any protracted occupation would face sustained guerrilla-style attacks.

Kharg Island — Geography, Significance, and Iran's Oil Export Architecture
Kharg Island (also spelled Khark) is a small island in the Persian Gulf located approximately 25 km off the coast of Iran's Khuzestan province. Despite its small size (~18 km²), it handles approximately 90% of Iran's crude oil exports. The island has been the hub of Iran's petroleum export infrastructure since the 1960s, featuring multiple Single Point Mooring (SPM) systems capable of loading supertankers, large oil storage tanks, and extensive pipeline connections to Iranian oilfields on the mainland. Iran is a founding member of OPEC (1960) and holds the world's third-largest proven oil reserves (~157 billion barrels) and second-largest proven natural gas reserves. Control of Kharg Island is therefore not merely strategic — it is the physical embodiment of Iran's ability to fund its government and project regional power.
- Location: Persian Gulf, ~25 km off Khuzestan coast; coordinates ~29°15' N, 50°19' E
- Area: ~18 km²
- Handles ~90% of Iran's crude oil exports
- Iran's proven oil reserves: ~157 billion barrels (3rd globally, after Venezuela and Saudi Arabia)
- Iran's proven gas reserves: ~32 trillion cubic metres (2nd globally, after Russia)
- Iran's production capacity: ~3.5–4 million b/d (significantly degraded by sanctions before 2026)
- OPEC founding members (1960): Iran, Iraq, Kuwait, Saudi Arabia, Venezuela
- Kharg Island was attacked repeatedly during the Iran-Iraq War (1980–88) — the "Tanker War" phase
Connection to this news: Kharg Island is functionally Iran's treasury. Seizing it would theoretically bankrupt the Islamic Republic, but the operational challenges of holding and running it — without Iranian expertise and under sustained counterattack — make it more of a strategic liability than the asset it appears on paper.
International Humanitarian Law and the Laws of Armed Conflict
The laws of armed conflict (LOAC), also called International Humanitarian Law (IHL), govern the conduct of military operations during war. Codified primarily in the four Geneva Conventions (1949) and their Additional Protocols (1977), IHL establishes key principles: Distinction (separating combatants from civilians and military objectives from civilian objects), Proportionality (civilian harm must not be excessive relative to military advantage), Precaution (all feasible measures to minimize civilian harm), and Military Necessity (actions must be militarily necessary). Under IHL, civilian infrastructure — including oil terminals — may only be attacked if they constitute a military objective, defined as objects that make an effective contribution to military action and whose destruction offers a definite military advantage. Deliberately destroying civilian infrastructure causing widespread, long-term environmental damage is prohibited under Article 55 of Additional Protocol I.
- Geneva Conventions 1949: 4 conventions covering wounded, POWs, civilian protection; 196 state parties
- Additional Protocol I (1977): extends protections to international armed conflict; India ratified in 1950 (original convention) and 2005 (protocols)
- Article 52 of AP I: defines military objective; civilian objects presumed protected
- Article 55 of AP I: prohibits attacks causing severe, widespread, long-term environmental damage
- Rome Statute of ICC (1998): war crimes jurisdiction; attacking civilian objects is a war crime
- ICRC (International Committee of the Red Cross): custodian of IHL; Geneva-based
- Proportionality assessment: military advantage must outweigh civilian harm — deliberately attacking Iran's main oil export terminal would face intense IHL scrutiny
Connection to this news: Any US military seizure of Kharg Island — rather than temporary strike — would require sustained analysis under LOAC principles. The combination of civilian workers, environmental risk from oil spills, and impact on global food and energy prices would make proportionality arguments legally vulnerable.
The Precedent of Iraq's Occupation of Kuwait (1990) and Its Consequences
In August 1990, Iraq under Saddam Hussein invaded and occupied Kuwait, annexing it as Iraq's "19th province" — the most naked seizure of a sovereign state in the post-World War II era. The international community responded with UNSC Resolution 660 (condemning the invasion), followed by Resolution 678 (authorizing force to restore Kuwaiti sovereignty). Operation Desert Storm (January–February 1991), led by a US-led 34-nation coalition, expelled Iraqi forces. The Iraq-Kuwait episode established crucial post-Cold War precedents: that territorial conquest by military force is categorically unacceptable under the UN Charter, that the UN Security Council can authorize military force to reverse such conquest, and that even states with security interests in the region will not tolerate unilateral annexations. A US seizure of Kharg Island — even temporarily — would risk being characterized in the same category: a major power seizing sovereign territory of another state by military force, with no UN authorization.
- Iraq invades Kuwait: August 2, 1990
- UNSC Resolution 660: demanded immediate Iraqi withdrawal (passed August 2, 1990, 14-0-1)
- UNSC Resolution 678: authorized use of force (passed November 29, 1990, 12-2-1)
- Operation Desert Storm: January 17 – February 28, 1991; 34-nation coalition
- Iraq set fire to 700+ Kuwaiti oil wells during retreat — massive environmental and economic catastrophe
- UN Charter Article 2(4): prohibits the threat or use of force against the territorial integrity of any state
- UN Charter Article 51: permits self-defence — the only recognized exception to Article 2(4)
- US seizure of Kharg Island without UNSC authorization would lack UN Charter legitimacy
Connection to this news: The Iraq-Kuwait analogy is the "ominous precedent" — if the US, the author of the post-WWII rules-based order, seizes a sovereign state's oil infrastructure by military force, it undermines the very norms it invokes against Russian aggression in Ukraine and Chinese aggression in the South China Sea.
