They don’t have the death penalty in Israel. There was a death ordered a while back and that was for Eichmann when he was captured by Israel. That was in May 1962! There have been none since then. The religious community in Israel is strongly against it. So ... you won’t get that in Israel.
Pollard was an American citizen then, and only an American citizen, when he committed his crimes, and then violated his plea agreement for those crimes, for which he is incarcerated, in America. America and its various states have the death penalty, irregardless of Israel’s only occasional use of it.
