The prohibition ‘Thou Shalt Not Murder’ applies only “to a Jew who kills a Jew,” write Rabbis Yitzhak Shapira and Yosef Elitzur of the West Bank settlement of Yitzhar. Non-Jews are “uncompassionate by nature” and attacks on them “curb their evil inclination,” while babies and children of Israel’s enemies may be killed since “it is clear that they will grow to harm us.”
