The ICJ case filed by South Africa I feel is the only concerted campaign I am seeing that pressuring Israel against committing genocidal settler colonialism (outside of the resistance by some Arab countries).
If ICJ is not a kangaroo court they will end up ruling their actions as genocide. The evidence is plenty.
Can any good come out of it? Or is it hot air?
Nothing. Israel is nothing more than Little Amerika-- and Amerika would never countenance being tried internationally.
