What are the phenomena of nationalism? Here are some of them: 1) National egoism, from which many other negative traits of nationalism are derived, as for example — a desire for foreign conquest, a desire to oppress other nations, a desire to impose economic exploitation upon other nations, and so on; 2) national-chauvinism which is also a source of many other negative traits of nationalism, as for example national hatred, the disparagement of other nations, the disparagement of their history, culture, and scientific activities and scientific achievements, and so on, the glorification of developments in their own history that were negative … And what are these negative things? Wars of conquest are negative, the subjugation and oppression of other nations is negative, economic exploitation is negative, colonial enslavement is negative, and so on. All these things are accounted negative by Marxism and condemned. All these phenomena of the past can, it is true, be explained, but from our point of view they can never be justified
