the only leverage HK protesters really have over Beijing is the prospect of their grievance finding its resonance in mainland cities. However given HKer's reputation nowadays one can safely assume that such leverage are not in play in the scenario at hand, which means the potential ramification of defiance and inaction by CCP is negligible. This is bad news for the protesters because they cannot continue to riot indefinitely. momentum in this kind of movement, especially one in which students are the mainstay, often run out quickly.
there is however another approach that can perhaps sustain this movement and even convince Beijing that it deserves proper attention. If the protesters were to occupy main government buildings and replace the city government's executive branch with the connivance or even collaboration from the city council, then Beijing will no longer be able to sit idly and watch. I have a good feeling that this is the path occupy central will eventually resort to if it finds itself to be losing momentum.
Not gonna happen. That's like, the most far-fetched and wildest possibility ever.
