Time isn't on Hong Kong's side. Frankly it was over when the Brits left. The question is Taiwan. They're capable of fighting back although when there time is on China's side
Hong Kong. You're right about that: the game was over the moment the ceremony ended.

If change is going to come, it has to come from deep within China. It's not impossible, but improbable for the time being.
If you look at it coldly, remove yourself from any partisan position, does the West
today really offer the other societies, with alternative takes on life, any outstanding moral highground? Frankly, there appears to be so much hypocricy, corruption and crime at all levels of its society, so much misery and squalor, social division and meanness of spirit... yes, possibly a higher standard of living for some, but beneath that, what?
