imperialism cannot exist without exploiting colonies and forcibly retaining them within the framework of the “integral whole”; because imperialism can bring nations together only by means of annexations and colonial conquest, without which imperialism is, generally speaking, inconceivable.
For communism, on the contrary, these tendencies are but two sides of a single cause-the cause of the emancipation of the oppressed people from the yoke of imperialism; because communism knows that the union of peoples in a single world economic system is possible only in the basis of mutual confidence and voluntary agreement, and that road to the formation of a voluntary union of peoples lies through the separation of the colonies from the “integral” imperialist “whole,” through the transformation of the colonies into independent states.
Hence the necessity for a stubborn, continuous and determined struggle against the dominant-nation chauvinism of the “Socialist” of the ruling nations (Britain, France, America, Italy, Japan, etc.), who do not want to fight their imperialist governments, who do not want to support the struggle of the oppressed peoples in “their” colonies for emancipation from oppression, for secession.

Even Stalin knew the western left was useless in 1924.
