UN is a political entity as you have hinted before in your previous comment. A state existing can best be measured by its acceptance through the UN usually, but even then one of the 5 imperialist powers can veto a state's recognizance proposal on their whims, and this completely nullifies it as a dependable metric. It comes to the example "All animals are equal, but some are more equal." from Animal Farm without any complexity governing it at all. It just doesn't cause many wars currently, although it does not help ease the stressful atmosphere. And where it causes war and suffering due to some imperial power on the other side of the planet exerting undue and unfair power over the peaceful talks between the sides, it becomes hell on Earth.

It is not better than the previous system if the already powerful can exert influence and claim interest in a local conflict it is not anywhere nearly part of. The strong still strongarm land-grab and killing, without the borders on the map not changing to their own name, but their pawns'. Adding a subterfuge element to it does not make the lives of the victims of the exploited region any more better, just suffocates through removal of oxygen rather than outright stabbing. In the case of Palestine, openly turns it into a concentration camp.

If only the US didn't veto any remotely fair resolution, or failing that proposals for heavy military sanctions against Israel for its genocide, the world could easily have ended this conflict decades ago. US could keep aiding Israel with technology and supplies related to prosperity rather than for one-sided war. Israel could still be a major powerhouse if their sugar mommy wanted, without having to actively expand land and kill innocent babies all around.

How is simply asking for Israel's statehood to be questioned and scrutinized, in the light of its continued genocide and invasion throughout generations and leaders, is asking for war? No such nation has a right to exist!
