To be fair, a lot of what we’re learning here is revolutionary theory. It’s theory, when applied, would lead to a revolution.
China’s already had their revolution. They don’t need to know how to start another one. They need to know how to protect itself from imperialism while advancing socialism. (Because it’s a third world country) One element of which is to be nationalistic, but in moderation.
If a revolution is to succeed in NA or the EU, we would have to take a different approach, as they are mainly first world countries. Nationalism in this context means to advance imperialism rather than to resist imperialism.
