> For a point of comparison, after Nazi Germany collapsed the Western allies had German civil servants fill questionnaires to assess their level of involvement; of 3.6 millions surveyed, just 1% were charged as "main culprits" (Hauptschuldige), whereas a third were designated as "followers" (Mitläufer), who basically contributed to the regime's crimes but nontheless got to keep their jobs after the war. I'd argue the allies were way too lenient on Germany, but the current Israeli approach (kill them all) is too extreme and will not work because its objectives are unrealistic.
You're comparing the Allies' actions after WWII concluded with Israel's actions in the midst of conflict.
Are you forgetting the Dresden firebombings?
Are you really suggesting that Israel will continue to "kill them all" if Hamas surrenders? That's not even what Israel is doing now, although they have the military capability to do so if they wished.
