ICC rules it has jurisdiction over West Bank and Gaza 'abuses' - BBC News
On the one hand a nice, if small, moral victory. On the other hand it is delightfully meaningless. Just as the Israelis thumb their noses at every other international institution, treaty etc. from their nuclear weapons programme to torture camps they will blithely ignore and and all rulings handed down. Thucydides quote on the matter continues to stand the test of time.
I actually wouldn't be surprised if we see the conviction and jailing of a mid level military officer or junior politician in the next 3-5 years. Now that is not game changing but it isn't meaningless.
