It’s the same concept where not even Taiwan claims they’re a sovereign and independent state: they’re the rightful government of all of China (including Mongolia).
And yet the argument was never “do these places need to be independent?” But “can China be trusted with dominion over space based on how they treat international waters and their neighbors.” You will notice that i did not specify any particular action or event. But you are already here with excuses for events and actions. Hence me mentioning that you are making my argument for me. Because you did that i already know, you know i am right to not trust china, and also you have a vested interest in me not being right.
