It’s actually pretty easy if you stop requiring support for settler colonialism. The rest of the world left that behind 70 years ago. Israel doesn’t get to be special they can either give Palestinians voting rights (which would obliterate the idea of a Jewish state) or submit to a UN peacekeeping force between them and the Palestinians on the 1949 borders.
The only reason this is hard is because we keep bending over backwards to support their Apartheid. We know these answers. They’ve been done before.
