Oh, there are many.
Look at the Banana Republics, entire countries ruthlessly operated by US banana companies.
Look at the numerous coups that the US orchestrated against democratic governments that weren't aligned to the interests: Iran (installing the Shah, arming him, convincing and aiding him to start a nuclear program), Vietnam, Nicaragua, Honduras, El Salvador, Cuba (unsuccessfully), Guatemala, Indonesia, and others.
Their support of/demand for Indonesian occupation and massacres in Timor.
Their support of Saddam Hussein's war against Iran (after the US-installed shah was deposed), including use of chemical weapons.
The numerous atrocities committed by the CIA all over Latin America, either directly or through the guerrillas they were controlling - in Nicaragua, El Salvador, Honduras, Guatemala etc.
The many war crimes against Vietnam, including slaughter of civilians, burning crops and forests, destroying civilian infrastructure and hospitals.
The unquestioning support of Israel's brutal occupation of Palestine, of Israel's possession of illegal nuclear weapons.
The direct support of Saudi Arabia's slaughter of Yemeni civillians, with arms, know-how, embargoes, and diplomatic means.
The long years of Black slavery in the US. Medical experiments on black troops. Forced sterilization of black men and women, and of those considered mentally unfit.
