Delusion: There were no North Vietnamese army units operating in either South Vietnam or Cambodia.
Reality:In order to maintain the delusion that the war was a popular uprising against imperialists, the “peace” movement could not admit that the war post-1968 was one of invasion from the outside. They labeled as lies any US assertions of invasion. Post-Cold War evidence proved the “peace” movement conclusively wrong. Post-Tet, all major combat was carried out by regular units of the North Vietnamese army.
