Of course they can revolt, and the Emperor/King/Chairman can drown them in blood. HK would a be a bitch to pacify, densely populated city with a ton of diaspora all over the world that can support insurgency with money, weapons etc. port that makes it easy to smuggle stuff in. See Irish troubles for an example of how these things play out. Nobody is going quietely into the dark night. You gone have to come and take them.
