Well, thanks for the history lesson, which most of them I already aware of.
The point is, how does it related to the current situation? Are you suggesting quoting history to the Israeli and have the issue solved? The point is, whoever you think is native in that land is beside the point, the reality of the situation is simple.
Palestine cannot get independence until 2 requirments were met.
1.) The world has to agree on.
2.) They will have to somehow remove Israel from those area.
You can tell me all day how many crime or war crime Israel committed, how people are being oppressed. How much those land were belong to whoever or where ever, or how far the terrorism goes? I can reply to your question in a Israeli point of view which you most likely would not consider that is legitimate and see that I am only saying that because I am pro-Israel, that's why I am not going to do that. So let's focus on simple question at hand and build it up.
What or how do you think these types of attack advance the situation between Palestine and Israel? That is the the major question to consider, unless your answer is "Screw Israel, they stole their land from us" Then this question has to answer, and if that is your actual answer, then I would have to say this will be an impasse between the two parties. You can't just ask them to go away because you think they are oppressing you, no matter how true that could be, you cannot demand people to support you because you think you are being oppressed, again, that's no matter how true it could be. Which means If you think that is a mistake Israel think they can hold on forever, then do tell me, what should they do then? Give up and go home? They can't, unlike US or Russian in Afghanistan or Vietnam, they think that's their home too. Whatever you said about the Arab is the same thing to Israel, and you think this is the right way forward?
Again, you remind me of that Palestinian UN Ambassador doing BBC interview. In it he said "Israel has been the oppressor to us for a very long time, and maybe this attack can galvanise the international community to do something with the situation" Yeah, if you want the international community to take action now, then any action they have will not be favor Palestinian. I mean, if you think people would be more incline to support your clause after this then I can tell you that you are really delusional.
