At root, the basic difference between anarchism and anti-state nationalism is that in nationalism the primary political unit is the nation, or ethnic group, whereas in an anarchist system the primary political unit is the local community or the place where labor occurs. Post-colonial anarchism is therefore clearly distinct from any form of nationalism in that it does not seek to make the nation a political unit - let alone the primary political unit. Just as social anarchists seek to create a socialist economy but oppose the tyranny of Marxist state socialism, post-colonial anarchists oppose the tyranny of nationalism, and argue that the achievement of meaningful self-determination for all of the world's nations requires an anarchist political system based on local control, free federation and mutual aid.
