By 1986, even the Vietnamese figured out that Communism was BS.
The problem in Vietnam is that the US decided to back the corrupt French colonialist regime forcing Ho Chi Minh into the hands of the Communists. It was just another cold war “cock up” by our State Deparment you know like making league with Pakistan rather than India because India wanted to pursue a course independent of the US. Our deepstate likes good puppets. Always has always will.
