Communism was fundamentally different from Fascist and Nazi ideologies in this sense: in spite of Stalin’s visibly prioritizing the Soviet state, Communist ideology was internationalist, not nationalist. It was authoritarian and ruthless, while at the same time appealing to global solidarity and social justice. Communists in Europe and elsewhere were often among the bravest and most unselfish opponents of Fascist dictatorships in their own countries, while refusing to speak out against oppression in Stalin’s USSR.
