I agree, the ICJ were clear here, Israel need to end their illegal occupation, evacuate all of their illegal settlers from the West Bank and East Jerusalem, end their systematic discrimination of Palestinians, their illegal exploitation of Palestinian resources stop violating their right to self determination and pay reparations for the damages caused by the occupation.
It's quite clear what Israel should do, it has been laid out by the international court of justice just what Israel should do. There is no 'what else can Israel do', what Israel can do is what they should have done a long time ago, start abiding by International law and pay reparations to try and atone for the untold pain they have caused.
