Oh please
There was no CIA when Rastafarianism started in the 1930s
They were no pal of neo commie Michael Manley in the 70s and 80s in Jamaica
Nor Eddie Seaga either
They did love Halie Selassie in Ethiopia now though
Rastafarianism as such was not started in the 1930's. It was not until the 1940's and 1950's when various movements were directed into socialist communes. First use of the word "Rastafarian" for the movement did not even appear until the 1950's.
Quite around the time of CIA's official formation.
