Mandate of Heaven is the realest of realpolitik. It's a political theory based entirely around results, with the added bonus of using faith and superstition to justify revolution against those who do not bring positive results.

So it cares absolutely nothing about idealism. Is the government capitalist? Communist? Monarchist? Democracy? Autocracy? Foreign Mongols? Foreign Manchus? Lizard people?

None of that matters. All that matters is do they deliver prosperity and peace to the Chinese people. Is everyone fed and rich? If yes, then Mandate of Heaven is achieved. If not, bring out the pitchforks and mobilize the masses, time for heads to roll.

That is so based.
