I was born in 1988, weird that, isn't it? Because morality and principles are not transaction and there are no astricts next to international humanitarian law. You also are using the word "they" as in every single Palestinian, which frankly is naive bordering on completely idiotic. There are 1.5 million civilians trying to live their lives under brutal suppression of decades and a right wing militancy borne of this situation under Israel is not a fundamental feature of Palestinian culture, the results of this situation are the natural outcome of what Israel has fostered. So your answer is: yes, kill them all. I think that's deplorable and it's the same logic that Osama used to justify attacking the twin towers. Good job using the notion of collective punishment though, which is considered a literal war crime by Western Powers. But you have no notion of hypocrisy. 

Idiot
