I specifically spelled out my call to action earlier in this very comment chain. Organizing with leftist parties like PSL and FRSO, revolutionary parties. Revolution is necessary, electoralism cannot work.

None of your examples started from a vaguely functional democratic state. For all the fawning over Cuba, somehow they are a big source of refugees.

Most of these refugees were historically land owning slavers, fascists, and Capitalists.

The Soviet Union fell apart under well understood conditions that their flavor of ‘communism’ did not fix.

Communism fixed a great deal of problems with Russia, why do you believe the USSR was dissolved?

China has an awful lot of forced labor, laborers stuck dorming in factories, and capitalist billionaires for a ‘communist’ state, and they have an ethno state with some other problematic human rights behaviors.

The PRC is a Socialist Market Economy. The model is described as a birdcage, the CPC allows markets to naturally develop but only along their guidelines, and increases ownership as competition creates these new monopolist syndicates. Socialism Developed China, Not Capitalism is a good article going over China’s economic model. The CPC has the power it has as a Dictatorship of the Proletariat, it needs that power to maintain supremacy over their bourgeoisie. Communism is achieved by degree, not decree.

While they may have been better than prior regimes in their contexts, I don’t think the end state in any of those is better than the current state of affairs in the US.

Why are you comparing developing countries to the current Imperialist hegemon? Do you think if you adopt Socialism, everything is magically fixed overnight? Have I ever implied that?

A good primer is Why do Marxists Fail to Bring the “Worker’s Paradise?” an excellent article that goes over materialist examinations of AES states vs idealist examinations. Another good reference is Blackshirts and Reds. AES is by no means perfect, but it does and did work.
