Here is the effect of ICC membership. A member state can complain about war crimes committed within its territory. I(n the case of Israel, an investigation by ICC will surely result in indictment of Israli leaders, at least for the crime of settling Israeli citizens in the occupied territory. Such indictees will not be able to travel freely, because lending in a state member of the ICC may result in arrest and transfer to the Hague. Occupation itself is not a crime. Violating the rules of occupation is. Incidentally, Syria and Lebanon are not members of the ICC. Unlike the Soviet Union, invented facts are not admissible in the West.
