I honestly can’t disagree with this. The UN is functionally useless and any effort on their part is wasted. The veto power of the permanent members makes it difficult to actually pass anything and even if they do pass the member states don’t really have to implement it back home.
The UN reminds me of the US under the Articles of Confederation, basically a toothless paper tiger. What doesn’t help is that the UN has passed quite a lot of resolutions and conventions which make basically any sort of conflict illegal and then admitted a bunch of countries which are actively opposed to each other. Admission to the UN should have been a lot more like the EU in my opinion, selective and binding.
Are you being coy? I would bet my life savings that the majority of Americans would feel unjustly attacked, that it was unfair, and every news station would be drumming up support for a military conflict. Pro-Gaza support in the US would disappear overnight (either silenced or fear of being silenced), Pro-Israel support would multiply, and the US would be flying drones down Gaza and the West Bank.
Remember that when 9/11 happened the US had been meddling in the Middle East for well over a decade already and had meddled with the Israel-Palestine conflict plenty. When 9/11 happened a majority of the world jumped on the side of the US. It’s possible that if another attack occurred it wouldn’t play out the same way (most likely because of Trump), but my guess is that it would.
