People who are just trying to govern themselves, rather than be governed. That's the heart of nationalism.

This is very wrong. Do you think nationalistic parties suddenly seize to be nationalistic in the moment they get the power to rule their country? Do you think that no government appeals to nationalism of their own people?

Nationalism is anything that appeals to members of a nation to defend a each other against a real or perceived threat. Nationalism of a national state gone big - China, Russia, Japan - becomes "imperialism".
