Any armed conflict demands awful moral calculations, weighing up the death and suffering of combatants and civilians from opposing sides. But not for Israel. They have a simpler approach: non-Israeli's (militant or civilian) count for naught.
We've seen dozens of innocent Palestinian civilians killed as reprisals for two Israeli soldiers and scores of Lebanese civilians killed for eight Israeli soldiers. Millions punished for the crimes of a few. Crucial civil infrastructure wiped out in very poor, damaged countries. Israel has regularly - for years now - shown us it is comfortable killing and maiming a dozen civilians to assassinate one militant.
Why on earth should they be trusted with nuclear weapons?
