Nationalism remains the #1 thing that must be fought against in the west. Unaddressed unconscious nationalism is at the root of all support for imperialism. The moment that people sweep away their nationalist brainworms and become an internationalist is the exact moment that they fully become one of us. Even when they are uneducated. Even when they know no Marx at all. Internationalism aligns anyone with us with no other feature necessary, absolutely every single thing we believe sprouts from the seed of internationalism.
