President Trump threatened on June 11 to seize Iran’s oil and gas facilities — including Kharg Island, which handles approximately 90% of Iran’s crude oil exports — a threat that, if executed, would require a massive military operation, create an unprecedented legal situation under international law, and transform the conflict’s character from a war about nuclear programmes into a war about control of Persian Gulf energy infrastructure.
President Donald Trump on Thursday said the US will hit Iran “very hard tonight” and later take over its oil and gas sectors. The latest threat comes after a second day of intensified strikes between the US and Iran, pushing the Middle East closer to the resumption of full-scale war.
Trump’s threat — made on Truth Social on June 11, 2026, during the second consecutive night of US strikes on Iran — is the most significant escalation of stated US intent since the war began on February 28. Previous threats have involved bombing Iranian power plants, a category of strike that would cause severe civilian harm but leave Iran’s territory intact. The threat to “take over” oil and gas sectors is categorically different: it describes military occupation of Iranian sovereign territory.
Whether the threat is a negotiating tactic or an operational plan is the central interpretive question. The history of this conflict suggests that Trump’s threats should be taken seriously — he threatened to bomb Iran, and he did; he threatened to maintain a naval blockade until a deal was reached, and he has. The threat to seize oil infrastructure is being heard in Tehran, Beijing, Moscow, and every Gulf capital with that track record in mind.
What Kharg Island Is — and Why It Matters
Kharg Island sits in the northern Persian Gulf approximately 25 kilometres off Iran’s coast. It is the hub through which Iran’s oil industry connects to the world. The island’s offshore platforms, onshore tank farm, and pipeline network handle approximately 90% of Iran’s crude oil exports — at pre-war production levels, roughly six million barrels per day.
Kharg Island was targeted by Iraq multiple times during the Iran-Iraq War of the 1980s. Its oil infrastructure sustained significant damage in those strikes. It was rebuilt and expanded repeatedly. Iran regards it as a national asset of existential economic importance — and has invested in its defence accordingly.
Under current conditions — with the US naval blockade limiting Iranian oil exports and the Strait of Hormuz partially closed — Kharg Island is not operating at full capacity. But it remains the physical infrastructure through which any restoration of Iranian oil exports would flow. Seizing it would not only cut off whatever residual exports Iran is managing; it would give whoever controls it — the US, in Trump’s threat — physical control over Iran’s future ability to export oil at all.
What Seizing It Would Require
A military seizure of Kharg Island would be a significantly more complex operation than the air and missile strikes the US has been conducting.
Air strikes — even the intensive 49-Tomahawk salvo of June 10-11 — do not require US forces to physically occupy territory. They damage or destroy specific targets and withdraw. The risks to US personnel are primarily from Iranian air defences that intercept or shoot down aircraft.
A seizure of Kharg Island would require:
Neutralisation of Iranian coastal and island defences. The island and its approaches are defended. Before landing forces, those defences would need to be destroyed or suppressed — a task that would involve further air and missile strikes, likely at significant scale.
Landing forces. US Marines, Navy SEALs, or Army Rangers would need to physically land on the island, secure the infrastructure, and establish a perimeter. An amphibious or helicopter-assault landing on defended territory involves military risks qualitatively different from stand-off air strikes.
Occupation and protection. Seizing the island is not the same as holding it. Iranian forces would attempt to retake it or destroy it. US forces holding Kharg Island would be subject to Iranian rocket, missile, drone, and naval attack indefinitely, in a confined location within Iranian weapons range.
Infrastructure protection. The oil terminals, pipelines, pumping stations, and storage tanks on Kharg Island are vulnerable to sabotage. Iranian forces — or the island’s own personnel — could destroy the infrastructure before a seizure is complete, eliminating the strategic value of holding it.
The Legal Status
The seizure of a sovereign state’s territory during an ongoing armed conflict, without UN Security Council authorisation and without the consent of the territory’s government, would be unprecedented in post-WWII international law.
Previous instances of one state seizing another’s territory — Iraq’s invasion of Kuwait in 1990, Russia’s annexation of Crimea in 2014 — were universally condemned by the international community. The US was the primary driver of the international response to both. A US seizure of Iranian territory would face similar condemnation from the same international community the US has spent decades insisting must respect the rules-based international order.
The legal argument the administration would make is that the seizure is a legitimate act of war against a country that has been attacking US forces and closing international waterways. That argument has some basis in the laws of armed conflict. It will not prevent the diplomatic firestorm that would follow.
The Geopolitical Consequences
The countries most immediately affected by a US seizure of Kharg Island are not the US and Iran. They are the countries that buy Iranian oil.
China has been the primary purchaser of Iranian oil throughout the war, using special arrangements to continue imports despite the blockade. India has also continued purchasing Iranian oil through bilateral arrangements. Russia, Turkey, and several other countries have maintained trade relationships with Iran.
A US seizure of Kharg Island would place the physical infrastructure through which China gets its Iranian oil under US military control. Beijing would not accept that outcome passively. The response — which could range from diplomatic condemnation to military support for Iran’s counterattack — would bring the US into direct confrontation with China’s most vital energy supply interests.
Russia’s response would be equally significant. Moscow has watched the Iran war as an observer and partial beneficiary — elevated energy prices have provided windfall revenues. A US military seizure of Gulf energy infrastructure would be experienced in Moscow as a direct demonstration that the US is prepared to use force to control global energy flows — a concern that has been central to Russian strategic anxiety about US power for decades.
Is It a Bluff or a Plan?
The honest answer is: we don’t know. Trump’s Truth Social threat was made in real time, without apparent prior coordination with allies or public advisory to CENTCOM. It may reflect a genuine operational intention to escalate to seizure if Iran does not agree to a deal. It may be a maximally threatening negotiating position designed to close the MOU that negotiators have drafted. It may be a combination of both — a genuine threat that is also a negotiating tool.
It is difficult to make a definitive call on whether this escalation will lead to full-scale fighting. For two consecutive nights, there have been US attacks on Iran, and the president says there will be more tonight if Iran doesn’t agree to a deal.
The phrase “if Iran doesn’t agree to a deal” is the most important clause in the current situation. Both Trump’s bombing campaign and his oil seizure threat are framed as contingent on the absence of a deal. They are coercive instruments designed to produce a specific diplomatic outcome. Whether that framing holds — whether a deal can be produced quickly enough to prevent the escalation from becoming irreversible — is the question on which the next chapter of this conflict depends.
