All the international signaling so far is that they're not willing to do anything about Chinese domestic issues. Other than a critical word (often not even that) at the UN, what have the EU / Russia / SE Asia / Arab states done?

And if no one is even willing to call China out on its shenanigans, why would they stop? They'll just get even more emboldened. HK, Tibet, Uighurs are resolved, so the next stop clearly is Taiwan. If Taiwan's independence is eroded and the US doesn't step in militarily, it's game over.
