Or if you, y'know, practice common sense.
Especially given all the countries you just mentioned have been at each other's throats numerous times. What kind of fantasy world do you live in where the USSR and China are both non-revisionist in spite of declaring the other to revisionist?
Anyways: Bolivia, Cuba, the DPRK, and Vietnam are regional powers at best rather than global powers and, with the possible exception of Bolivia, don't have a literal bourgeois class with capital worth billions of dollars to throw around.
China isn't some small state defending itself from colonial aggression: it's a power in its own right and is obviously advancing towards competing with other imperialist powers around the globe.
Also the DPRK is a monarchy.
