This isn’t kicking them because they suck. It’s because they keep killing envoys of the UN. I’d say murdering the citizens of your partners over and over is grounds for removal.
No, I’m not. I must not get some key element because I’m 100% serious. The headline says that Israel shot upon a UN convoy. How is my saying that should get them kicked out of the UN a deliberate misunderstanding of anything? Repeatedly shoot at the coalition of which you’re a member and you cease to be a member. That’s pretty straightforward.
Then strip them off every benefits and voting power in the UN. They can be there if they wanna talk peace or listen.
