Hong Kong was always going to happen because that was an agreed upon conclusion. China violated promises that it made (one country, two systems my ass), but Hong Kong was a part China. Taiwan has never been under the control of the current government of mainland China. At this point Taiwan would likely be a separate country if it didn't have China's dagger at its throat telling it that even a breath of declaring independence will result in immediate invasion.

Reunification will happen, like Hong Kong.

I don't remember Hong Kong starting WW3 though. 🤔
