Socialist Internationalism and the Ukraine War

How do the working people of the world transform themselves from a plethora of groups waging a multitude of scattered struggles for survival and dignity to a revolutionary force capable of ending capitalism, governing the earth, and taking over production? They have innumerable tasks before them, but one of the most important is to overcome divisions among themselves resulting from ethnic supremacism and nationalism. Marxists have been debating this issue from the beginning, but it still plagues us today. The war in Ukraine offers a good opportunity to examine it more closely.
