Well that can't be true, the UN is the ultimate arbiter of international law, member states
acknowledge that when they sign the charter and become UN members.

Resolution adopted by the General Assembly on 30 December 2022
This is a fraction of the total historic collection of resolutions demanding Israel stop acting unlawfully.
Now you might, as some do, state that Israel does not respect these resolutions, that they UN is acting prejudicially and that Israel alone decides what is lawful and legal. But as soon as you do that you face the situation where Hamas too can take that same view. If Israel does not want to hear such view from the UN it could just leave the UN, nobody's stopping them.
This is in fact was has been happening since 1948, Israel disregards the UN, disregards international law and continues its crimes and because the USA vetoes any possible steps to penalize Israel the crimes go on, year after year after year. Faced with that Hamas and Hezbollah and other also disregard the law.
If the US would stop flogging a dead horse and do the right thing, Israel would be sanctioned and forced to obey the UN just as was done with
Saddam Hussein's Iraq for example.
This is what needs to be done, else Israel's military bases should be bombed.
No, it's always had a large Christian population (its in the heart of the historic Christian world) both before and after Islam came to exist.
