The US under Trump is going to pull out of the Paris Climate Agreement and probably no longer going to COPs. They are the biggest supporter of Israel and climate reparations are going to be a very hard sell, with the largest historic emitter not paying anything at all. Actually it is even worse as the US already is giving less then other historical emitters. So best case is that mainly Europe pays for the US share as well and stops its support for Israel.
Also the headline is deliberatly missleading. Gaza is obviously not a massive topic at a COP.
Man muss trotzdem nicht die Bürotür für einen getreuen Putins öffnen.
