United States - Operation Breakfast

From 1970 to 1973 a massive United States bombing campaign against the Khmer Rouge devastated rural Cambodia. An earlier U.S. bombing campaign of Cambodia actually started on 18 March 1969 with Operation Breakfast, but U.S. bombing in Cambodia started years earlier than that.

The number of Cambodian civilian and Khmer Rouge deaths caused by U.S. bombing is disputed and difficult to disentangle from the broader Cambodian Civil War. Estimates range from 30,000 to 500,000. Sliwinski estimates that approximately 17% of total civil war deaths can be attributed to U.S. bombing, noting that this is far behind the leading causes of death, as the U.S. bombing was concentrated in underpopulated border areas. Ben Kiernan attributes 50,000 to 150,000 deaths to the U.S. bombing.
