The US government is the absolute arch enemy of anything actually socialist. To construct some weird ass reasoning, that any kind of foreign interference amplifies that very fringe aspect of US society is … man, I would argue that you‘ve got brain worms (but more likely a default western mind, which you yourself are the master of, if only you dared).

The US population is conditioned to reject anything labeled socialist since the Russian revolution in 1917, the very moment the proletariat brought the evidence, that the exploited class is able to govern itself. That radiated internationally, as evidenced by the establishment of communist parties in the following years all around the world.

The US elites, panicked a worker’s revolution could threaten their rule, and immediately joined forces to invade Soviet Russia to try and put an end to that (but failed). The US did not recognize Soviet Russia until 1933, in fear to legitimize the Bolsheviks.
The US immediately started its domestic red scare propaganda and repression of anything vaguely critical of the government, so mostly anarchists, communists and worker unions.
The US/CIA ever since has been the main actor to topple and squash any attempts of socialism (or otherwise unaligned rule) by force, going as far as to genocide the native population, see Korea, Vietnam, where it slaugthered millions. It‘s using military force, interference and coups until today.
The reason there even was a Cold War was, because the US capitalist class was scared that the communist idea would tale hold and thereby forced the war ridden and slaughtered Soviet people into an perpetual arms race so it wouldn‘t be abble to get crushed by the US war machine. Resources that would have been needed in other places.
US propaganda is the very reason, that nowadays a bunch of so-called socialists hold the conviction, that communism is somehow bad or evil, because it put a lot of energy into building that narrative.
The US produced the so-called Compatible Left to pacify the movement, so it wouldn‘t grow to become a danger for the ruling class. A philosophical poison throughout the western hemisphere.

No foreign actor needs to add a drop into the ocean that is US anti-communism, that‘s the definition of a wasted effort. The USA IS anti-communism by being the capitalist world hegemon. US-Americans fully support capitalism, because it‘s their domestic ideology, their only conceivable reality. Their country and their system has become the sole ruler of the world (or, has been as of lately) ever since the Soviet Union as a counterweight vanished. That‘s also a good chunk of the reasons why the world has been in constant crisis ever since. They really don‘t need Russia for any of that.

I’m absolute certain, that you have absolutely no fucking clue, what you are talking about. Would you be an LLM, we‘d conclude that you are hallucinating.
