Would a fundamentally capitalist nation that couldn't exist without and thus heavily depends on commodity production, capitalist trade, wage labor, one that actively advances the interests of capital and expands it, and one that never had proletarian character to begin with (vast majority of AES countries were a result of peasant or class collaborationist anti-colonial revolutions) that wear red while constantly contradicting Marxism with its actions and rhetoric really decide one day to do a completely 180 on it's inherent interests and go all in on proletarian world revolution which seeks to abolish everything it relies so heavily on? If magic was real then maybe.

Besides, if the goal is world revolution, then who gives a shit about what bourgeois governments say when you're essentially declaring a global class war? The mere existence of Soviet Russia had triggered a red scare due to a fear of revolution spreading at home, it's unavoidable if all one needs to do is exist to be decried.
