Are you trying to argue that laws and treaties are worthless unless enough people abide by them and are willing to enforce them?
Because, yes, that is the fundamental principle of society: We need to work together to survive and thrive, so we agree on rules by which we work, and enforce them on those that break them. If you disagree with something but take no steps to oppose it, your disagreement is just as worthless as a law nobody cares to enforce.
So what point are you trying to make here? “If China enforced their claim and nobody stopped them, their claim would be effectively valid”? How is that relevant to the situation if all they’re doing is protesting, but nobody else cares to back them up and they don’t actually take measures to prevent the passage?
“If I put pineapple on my Pizza and nobody stops or punishes me, it’s legal”? Yes. Congrats. You understood the very basics. Want a sticker?
Can we have both? A concise textual description and a video exemplifying the features?
