It’s a bit incomplete to bring up Security Council vetoing without mentioning Russia (currently at war with a sovereign nation) and China (intent on war with a sovereign nation).
The UNSC isn’t an arbitrator of good, but an alignment of hard UN outcomes with the first countries to have nukes (and therefore the ability to force the issue militarily if they disagreed with the UN).
This is not proven. Why would China want to wreck Taiwan? Official US, Taiwanese, and Mainland China policy is that there is one China. Taiwan is like Texas being a breakaway republic run by confederates in the USA, though the culture has evolved in a more progressive direction (more progressive than USA) since the original breakup.

I'll give you that's bad, but at least it's a fight between nations and not a genocide. I believe the U.S. instigated this fight by advancing NATO territory eastward and my position is there should be peace negotiations immediately.
For the same reasons most wars have been fought: belief (primacy of CCP), resources (uncontested access to the Pacific), and the economy (don’t worry about that, ra ra flag).
> [Russia and Ukraine] not a genocide
One of the definitions of genocide is forced relocation of children and eradication of culture, both of which Russia is doing in the Ukrainian territories it occupies.
