It said the Israeli leader was covered by immunity rules that apply to states which are not a party to the ICC. Israel is not an ICC member.
“A state cannot be held to act in a way that is incompatible with its obligations in terms of international law with regards to immunities granted to states which are not party to the ICC,” the French statement said.
While this technicality may be true, it still seems like there should be a mechanism to hold people accountable for genocide that they don’t have to agree to beforehand. Saying “oh we can’t arrest him for crimes against humanity because he didn’t already agree to be arrested for them should he ever commit them” is a diplomatic copout and a moral failure of the international framework.
It isnt even technically true. The ICC has already clarified that this does not refer to the arrests of individual heads of states, but rather seizing states assets and the like.
