The Vietnam War myth

[bwv]

Communism is used as a catch all phrase, the West, you see I say the West, defense of Greece was to counter Stalinism which is not Communism. Semantics for some, but if we're talking truth to history we should try to be clear with one another.
Maoism is another abomination of Communism. Stalin and Mao, in their quest for power by expansionism became dictatorships under the guise of "Communism".

As opposed to all those other communist governments that weren't dictatorships?

Stalin did nothing that did not have a precedent with Lenin. He after all created the terror apparatus that enabled Stalin to consolidate power.
