I'm not arguing that the #UN should exist, although I think it should. I'm not even saying that they should have rebooted #Israel in 1948. What I'm saying is, the #UN isn't useless. Even if you don't like the #UN, they effected change, and bad people doing bad things aren't useless by virtue of their badness.
The #UN has done a lot more than hold #Israel together BTW, that was just the first example that came to mind.
