I normally enjoy the Rosendo's Travelscope show on PBS but his recent political comments about Cambodia were harmful nonsense.
US bombing caused the Khmer Rouge genocide.
That is the equivalent of saying that:
US bombing caused the Nazi genocide.
Both statements are ridiculous lies. Disgusting disinformation. The Khmer Rouge and the Nazi's are to blame for their genocide, not the United States.
The US supported the South Vietnam, Cambodia and Laotion governments against Communist attacks. Our support included bombing of their strongholds and supply lines.
