No.So... by your comments I gather you understand that:
-In China, the "rules" were not upheld because the UN is broken.
-In Africa, the "rules" were not upheld because the UN is broken.
-In Iraq, the UN said Iraq must allow inspectors in, but never authorized any sort of war, which we subsequently carried out unilaterally.
-in SA, you claim we followed a rules-based approach because our president unilaterally signed a document saying it was ok. I'm sure Putin did that with Ukraine, too. That doesn't mean we get carte blanche "legally" to overthrow foreign governments because we don't like their current one.
So, if the rules are repeatedly broken and not enforced, how do you consider them rules the world lives by?
You say that each nation has an obligation to stay within international law. Says who? Who obligates them? Who smacks them if they don't? The UN? Unless you know something every international relations student and expert knows, there is no higher international authority than the nation-state. They answer to nobody, except the more powerful nations that might smack them if they do something they don't like. Any "legal and moral rationale" is just how the leaders justify the actions to the public and other states. They are not bound by any higher power to do anything by any legal code.
Lastly, your graphic is one of the worst non sequiturs I think I've ever seen. The fact that fewer people have died in war since WW2 is absolutely not because of the UN or whatever "rules based order" you think it represents. It is because the largest, most powerful countries have nukes, and aren't stupid, with a few smaller contributing factors like globalization. That is obvious to anyone who has studied this stuff for even a minute, which I know you have. I'm baffled.
No.
No.
No.
You can be as ignorant and obtuse as you desire, but I was very clear in my comments. You are getting significant push back in this discussion because you are being willfully ignorant.
