Grade 3 of 5: Serious Rights Violation
The US was the sole dissenter blocking Gaza ceasefire resolutions supported by all other Security Council members, while famine and allegations of genocide continued in Gaza. The pattern of vetoes enabled continued military operations with devastating humanitarian consequences.
Grade 4 of 5: Critical Rights and Rule-of-Law Concern
The Trump administration backed and funded a privatised aid scheme in Gaza whose four sites became scenes of near-daily shootings of hungry people, overwhelmingly by Israeli forces. The UN counted 859 killed near GHF sites in its first two months. The US approved $30 million for GHF after the killings were known. Whether that support amounts to complicity in war crimes is plausible but not established.
Grade 4 of 5: Critical Rights and Rule-of-Law Concern
Israel deployed white phosphorus over Lebanese civilian areas in 191 reported attacks across 17+ municipalities since October 2023, continuing through March 2026; US-supplied munitions were identified in the October 2023 Dhayra attack. HRW found the March 2026 Yohmor use unlawfully indiscriminate and called on states, including the US, to suspend arms transfers. US criminal complicity in the 2026 attacks is not shown.
Grade 5 of 5: International Crime (Rome Statute)
Trump's first foreign trip was to Riyadh, where he announced a $110 billion arms deal with Saudi Arabia. The U.S. continued to provide refueling, intelligence, and targeting support for Saudi-led coalition strikes in Yemen throughout the first term, even as the UN documented mass civilian casualties, attacks on protected sites, and a blockade causing mass starvation. Congress passed a War Powers resolution to end U.S. involvement, which Trump vetoed in April 2019, and he vetoed three resolutions disapproving arms sales in July 2019.
