The parts you quoted were about self-defense and stopping the fighting, not about the ownership of the islands.

I quote it because it also talks about negotiations that should be begun when it comes to the ownership of the islands, in lieu of continuing the fighting.

I'm already on record about stating that the fighting was wrong, though I don't know how long anyone would expect a nation to wait for a diplomatic solution.

This press release from the UN goes into more detail on the basic structure of what I'm arguing about: https://press.un.org/en/2021/gacol3347.doc.htm

(I really shouldn't bother with attempting nuanced conversation on the Internet, it never ends well.)
