UN is just a voluntary group activity discussion form, that's all, not some objective stand-up world police.

Any UN-wide military intervention would require some consensus from at least some of the major powers on the security council, but Israel is being shielded by powers such as US and Germany so nothing will happen at UN level, especially when those two countries are known for applying sanctions on people and countries who are boycotting Israel and aiding Palestine.

There are a few countries very vocal against what Israel is doing, but obviously none of them will go as far to send troops to that region by themselves, which is understandable for multiple reasons, especially given the already elevated economic and geopolitical challenges around the world right now.

The “international community” also tolerates the USA invading Iraq, Iran, Venezuela, and all their other adventures. And tolerates Russia invading Ukraine. etc etc etc with many other countries’ adventures. Why expect different here?

Israel has a universal get-out-of-jail-free card for everything called "shout 'antisemitism'". Say anything even mildly critical of anything the Israeli government does and you get 'antisemitism' shouted at you. There are even antisemitic Israelis, meaning ones who have dared to criticize what their government is doing. It's so depressingly predictable, it's the automatic response every single time.

US Gov would veto that shit
