The rest of the world is scared of even offending China by calling Taiwan a country. You really think they’re going to go to war over Taiwan?

They’re not really scared of offending China, they’re scared of triggering that war. If China triggers that war all the hesitancy will be gone.

That said, I’d expected more of a reaction to the annexation of Hong Kong too.

Hong Kong was not "annexed". It returned to China's control from the UK by treaty.

"One country, two systems" is being curtailed early, but that is harder to argue against without a foreign power there to do anything about it.

Ok, down-voters.

How is my statement about the Sino-British Joint Declaration incorrect?

Yes.

War with China is not possible because of nuclear weapons. China can do anything to Taiwan. And China size will make sanctions essentially useless (especially because half of the world will not join those sanctions).
