US-Backed Actors

Data Sources

Compiled from truth commission reports (Guatemala CEH, El Salvador, Chile Rettig/Valech, Argentina CONADEP, East Timor CAVR), Human Rights Watch, Amnesty International, Congressional Research Service, and academic sources cited per event.

Death Toll Estimates

All death tolls are shown as ranges (low estimate - high estimate). Deaths counted are those committed by the US-backed regime during the period of US support — not deaths caused directly by US forces (those are on the Interventions map).

The causal relationship between US support and the regime's violence varies: in some cases (Indonesia 1965, Guatemala, El Salvador), US support was directly enabling. In others (Egypt, Tunisia), the connection is more indirect.

Presidential Attribution

Support is attributed to the president in office when US backing began. Death toll is distributed evenly across the years of the killing period and attributed to the sitting president each year.

A president who maintains support for a repressive regime is attributed deaths that occur during their term.

Scope

Significant US military aid, arms sales, intelligence cooperation, financial support, or diplomatic cover provided to governments that committed systematic human rights abuses during the period of US support.

Limitations

• Death tolls are inherently uncertain, especially for long-running dictatorships.
• The degree of US responsibility varies from direct enablement to passive acquiescence.
• Some entries are marked "contested" where the nature or extent of US support is debated.
• This is not comprehensive. Many US-backed regimes are omitted where deaths were not reliably documented.
