It's funny/sad. When UAE signed the Geneva convention their terms were we promise not to commit genocide as long as you promise you don't have jurisdiction to prosecute us through the ICJ.

That's my reading as well. I have no idea what is actually in Article IX but it sounds like UAE snuck in "except us" when it came to defining the ICJ's jurisdiction. It's giving SovCit vibes, only instead of a sovereign citizen unbeholden to their government and declaring their house a nation state, it's a country unbeholden to the world and declaring themselves outside of its purview. And the ICJ is just shrugging their shoulders saying the same thing.

Imagine someone shooting up heroin while driving, getting pulled over on a highway on-ramp, then telling the cop who is looking at the needle in their arm that technically this is a highway, so highway patrol are the only ones who could pull them over. In what world does the cop shrug and say "Aw shucks, you're right" before getting back in their squad car and driving off? Because it seems like the international equivalent of that just happened but with genocide instead of addiction.
