In WWII the Germans ran into much resistance in occupied lands, as is well known, and the resistance fighters did their level best to kill Germans and destroy certain infrastructure that was useful to the Germans. They launched what the Germans saw as "terror" attacks. The Germans often retaliated by killing 100 of the local people for every dead German. They had the firepower and the means to easily do that. They reasoned that this would dissuade the resistance fighters and the general populace from further attacks upon Germans. That turned out to be dead wrong. It simply provoked further violent attacks upon Germans. Apparently the bitterness and anger caused by the German reprisals made the resistance quite willing to face those disproportionate losses of 100 to 1 in order to continue hurting the Germans.

The Israelis have just killed about 300 people over an attack by Hamas which killed, what was it? 2 people?

That's a similar method to the German method of massive overkill, and I predict it will yield a similar result. Massive retaliation by Israel makes Israelis feel good, but it does nothing to end the conflict, it only guarantees further primitive pinprick terror attacks by their poorly armed Muslim opponents.

As for the Muslim fighters, their guerilla tactics do nothing to end the conflict either...they only guarantee further high tech massive overkill terror attacks by Israel, and much more suffering and waste on both sides.

So they are both engaging in stupid, pointless, tit for tat violence which will solve nothing. I see no reason why either of them should be proud and beat his chest over his latest act of violence. I see no reason why anyone here should support either one of them for doing so.
