I'm aware that the US Empire took advantage of the Sino-Soviet split. As I said, it was a tragedy, and a mistake. However, this does not mean China's socialism is invalid or wrong. I do not see any double standards on my part, can you explain quite clearly what they are? I value both Stalin and Mao greatly. Both made mistakes, but both were critical for the establishment of socialism.
Later Mao made more mistakes than earlier Mao. This is why the Gang of Four took power, causing all manner of confusion, and resulted in Deng Xiaoping courses correcting. Reform and Opening Up ultimately was done in a manner that the US thought they could exploit, but in reality the CPC maintained control and the US Empire's plans are failing. This is why the cold war against China is ramping up.
