A land war against China over Hong Kong would be ridiculous. They have the entire country as a base. The western countries would have to fly/sail everything in.

A land war against China over Hong Kong would be ridiculous. They have the entire country as a base. The western countries would have to fly/sail everything in. Not to mention the legal situation. It's their soil already. It would be an invasion. Against another superpower no less. Really bad idea. And China can hurt the city enough by just turning the water off. It will only hurt the people of Hong Kong more. No, this change won't be driven by the military. It will have to come from within. Probably the most durable way anyway (see how this worked out for Afghanistan). Taiwan would be a totally different thing though. They have been independent for so long and they have no wish to join communist China (which they've never been a part of). And it's much more defensible. I do hope we will stand by them when it comes to it.
