And the Hawaii stuff has exactly what to do with China? Oh wait, it doesn’t. The US being “nice” isn’t even part of this discussion. And really, neither the PRC or ROC have any leg to stand on when it comes to accusations of atrocities.
As far as the rest, none of that matters. Does the PRC control Taiwain now? No, no it doesn’t. Has the PRC controlled Taiwan for all these decades it’s played this game of pretend? No, no, it hasn’t. Until the PRC has actual control over Taiwan, its claims of ownership are meaningless.
