The only problem that socialism ever had is that you could run out of money from capitalist nations trying to overthrow your government while the best resource to generate energy and therefore money is coal, which most socialist nations don't have in abundance but settler-colonial capitalists ones do from it's imperialist run during colonial times.

But we don't live in those times anymore. It's the 21st century, solar and wind is gaining ground, and therefore China is rising, which it already was because its inferior coal became affordable somewhere during the 20th century.

It's actually amazing that no new socialist revolution has happened yet and yet plenty of nations tried to and even succeeded in going further to the right, going neo-liberal, neo-conservative or even fascist, and that includes attempted or even succesful coups, even in China itself with the failed attempt in Hong Kong and a neo-liberal push in Taiwan, to stop the older nationalist party from surrendering to the winning socialist party of China in its civil war, and just rewrite history to pretend they never were Chinese in the first place and that they are the native people of Taiwan instead of the Pangcah, Atayal, Paiwan, Rukai and Dunnan among others.

And this is all happening during a complete socio-economic meltdown around the world due to AI,
that should be ushering in socialist nations into becoming full communist.
