Incidents related to military escalation, threats of force, or armed conflict involving Iran, including airstrikes, sanctions designed to provoke, and violations of the UN Charter's prohibition on the use of force.
The Pentagon's own Inspector General found that Hegseth gutted every single legally required civilian harm mitigation program during an active war. Zero objectives met. 133 required actions incomplete. Civilian harm staff cut by over 90%. The Army's casualty-tracking database defunded. Released the same day CENTCOM admitted it had no way to investigate hospital and school strike reports.
Trump rejected Iran's peace proposal, called the ceasefire 'on massive life support,' and had a 'very major attack' planned before Gulf allies talked him out of it hours before execution. Congress was not consulted. Vance publicly declared the US 'locked and loaded.' The episode reveals war-making conducted entirely at presidential whim, with no legal or democratic check.
U.S. strikes on civilian port cities (Qeshm, Bandar Abbas, Bandar Kargan) during an active ceasefire killed at least one sailor, injured ten, and Iran says hit civilian residential zones. A massive oil spill (71 sq km, ~80,000 barrels) from Kharg Island was confirmed by Copernicus satellite imagery. Iran declared the ceasefire violated and said the U.S. had 'crossed the point of no return.'
Trump launched a Navy operation to force ships through the Strait of Hormuz during an active ceasefire without notifying Congress. Iran attacked three US destroyers. Saudi Arabia then denied US airspace access, collapsing the operation. The 'pause for negotiations' cover story was contradicted by reporting that Saudi Arabia's airspace denial made the mission militarily impossible.
The United States imposed a full naval blockade on all Iranian ports after peace talks in Islamabad collapsed, threatening to destroy any vessel approaching. The blockade — the first U.S. naval blockade since the 1962 Cuban Missile Crisis — constitutes an act of war under international law, threatens 25% of global seaborne oil, and amounts to siege warfare against Iran's 88 million civilians.
Trump's threat to jail journalists for reporting on a military rescue mission during the Iran war extends the administration's documented pattern of using national security claims to suppress press freedom and criminalize journalism.
Trump's explicit threats to destroy all civilian infrastructure in Iran — every bridge, every power plant — with the stated goal of ensuring Iran 'could literally never rebuild as a nation again' constitute textbook threats of indiscriminate attack, a war crime under the Rome Statute and customary IHL.
The shootdown of a US F-15E over Iran and the massive rescue operation that followed document the intensity and cost of the 2026 Iran war. The rescue itself was a legitimate military operation, but Trump's threat to jail journalists who covered it raises serious press freedom concerns, and the scale of the operation — including abandoned US aircraft inside Iran — illustrates the escalatory trajectory of the conflict.
US forces destroyed Iran's landmark B1 bridge near Karaj in a double-tap strike during Nowruz holiday celebrations, killing 8 civilians and wounding 95. The bridge — 176 meters tall and 1,050 meters long — was under construction and had never been used for any military purpose. The strike marked the first direct hit on major civilian infrastructure following Trump's 'Stone Ages' threats.
Repeated strikes near Bushehr nuclear power plant violate Additional Protocol I Article 56's specific protection of nuclear electrical generating stations. Even without a radiation release, strikes on or near an active nuclear reactor in a city of 250,000 constitute reckless endangerment of the civilian population and violate the prohibition on disproportionate attacks under Rome Statute Article 8(2)(b)(iv).
The US Defense Secretary's public declaration that no quarter would be given to Iran constitutes a textbook war crime under Rome Statute Article 8(2)(b)(xii), which criminalizes 'declaring that no quarter will be given.' This prohibition is among the oldest in the laws of war.
U.S. military strikes on Kharg Island — Iran's primary oil export facility handling 90% of crude exports — constitute attacks on critical civilian economic infrastructure. Combined with explicit threats to destroy the entire island, these strikes raise serious questions under the proportionality and distinction principles of international humanitarian law.
US and Israeli strikes have damaged UNESCO World Heritage Sites and over 100 cultural heritage sites across Iran, including Golestan Palace, Isfahan's Naqsh-e Jahan Square complex, the 8th-century Jameh Mosque, and prehistoric sites dating to 63,000 BC. The destruction of cultural heritage during armed conflict is prohibited under the 1954 Hague Convention and constitutes a war crime under the Rome Statute.
A US submarine torpedoed an Iranian frigate returning from a peaceful international naval event, killing 87 sailors. The failure to rescue shipwrecked sailors violates the Second Geneva Convention's obligation to search for and collect the shipwrecked after an engagement.
The Iran war triggered closure of the world's most critical energy chokepoint, causing the largest supply disruption since the 1970s. Despite a nominal ceasefire, the US and Iran exchanged fire in the strait on May 7, 2026. The US struck civilian port cities Qeshm and Bandar Abbas; a cargo vessel was hit, killing one sailor. A massive oil spill (71 sq km, ~80,000 barrels) from Kharg Island confirmed by Copernicus satellite imagery. Iran declared the ceasefire violated; the strait remains effectively closed.
Trump's explicit threat to destroy Iran's civilian power infrastructure constitutes a per se violation of international humanitarian law. The threats escalated from 'obliterate' to a promise of 'complete demolition' of all civilian infrastructure. Combined with 3,400+ killed including 1,600+ civilians, this represents a confirmed war crime classification.
The United States launched a major war against Iran without congressional authorization, without a UN Security Council mandate, and while diplomatic channels remained open. Legal experts, the Brennan Center, and international law scholars have characterized the strikes as unconstitutional and as potentially meeting the definition of a crime of aggression — what the Nuremberg Tribunal called 'the supreme international crime.'
A sustained pattern of strikes on Iranian hospitals, ambulances, and medical infrastructure has killed healthcare workers and forced the evacuation of six hospitals. The WHO verified 18 attacks on health sites through mid-March 2026, documenting systematic damage to protected medical facilities including Gandhi Hospital and Iranian Red Crescent centers. The pattern continued through the April 7 ceasefire, and HRW documented further strikes through the ceasefire period in its April 2026 report.
A Tomahawk cruise missile struck a girls' elementary school in Minab, Iran, killing up to 180 schoolchildren in one of the deadliest single incidents of civilian harm in the 2026 Iran war. Investigations by the New York Times, CBC, NPR, and BBC Verify confirmed US responsibility.
DOGE's elimination of the State Department's energy diplomacy bureau months before the Iran war left the U.S. without key personnel who monitored energy chokepoints, oil markets, and Iranian energy infrastructure — capabilities now desperately needed during a conflict centered on the Strait of Hormuz and Iran's oil economy.
The Pentagon's civilian casualty prevention infrastructure was gutted in early 2025, removing safeguards that existed specifically to prevent the kinds of civilian harm documented in the administration's subsequent military operations.
Using emergency waivers under the Arms Export Control Act, the administration has bypassed Congress to approve massive arms sales to Gulf states, including to the UAE despite documented evidence of UAE weapons flowing to the RSF in Sudan's genocide. The simultaneous rescission of NSM-20 removed all human rights conditions from US arms transfers.
