Opposing rebels should fight each other, and maybe in certain circumstances form coalitions (e.g. communists join with certain nationalists to fight fascists sometimes etc)
Maybe even have a "will ally with" list per country similar to the party system. So that there's more and less hardline rebels (like for instance fascists or communists that will or will not accept the demands of nationalists and ally with them) of various types in different countries to add flavour.

With tariffs, how about two seperate sliders for raw goods and manufactured goods? No doubt there were some countries that made raw goods cheap and manufactured goods expensive or near impossible to import.
