Abstract
Socialism, which began in a historical world situation, has its serious flaws. It has not fulfilled Marx's prediction that the world revolution would first take place in countries with the most advanced productive forces; nor has it proven Lenin's foresight that, once the weakest link was broken, the whole chain would be smashed and the world revolution would break out. Proletarian revolution with socialist characteristics takes place one by one, in some backward countries over a relatively long period of time. This distinguishing feature is mostly determined by the imbalance in the development of the world. It has also created obstacles to continuing the socialist revolution in these countries after the revolution is won in these countries. Marx and Lenin were unable to conduct in-depth investigations of the backward regions of Asia, Africa, and Latin America. Consequently, they were unable to predict to what extent such an imbalance would have an impact on socialist revolution around the world
