Not at all. The Jews would have been completely justified in defending themselves against the oppressing Germans. But in the same way, the Palestinians are justified in defending themselves against the oppressive Israelis. I see little difference.
If that was all they did, then there would be no problem. But they are oppressing those people who were there before them. In particular, they consciously and deliberately keep the Palestinian economy unfunctional.
You took the lands from those who were already there. Your claims to a 2000 year inheritance are irrelevant.
No offense meant Polymath, but this of yours is simply ignorance of History. Before 1948 which was the year when the Jewish State was proclaimed There were so many Jews in Israel as being the majority in some cities. Jerusalem for example. When the Romans forced the Jewish People into exile do you think they expelled every single Jew? Wrong again if you think so. More peasant Jews stayed in the Land than were exiled from the Land. And only 700 years later the Arabs came. So stop this nonsense that we took "their" land because you are only giving credit to historical lies. Besides, much of the land was paid for to "Palestinians" trying to make some easy money. And guess what? Sometimes the Jews had to pay twice the local settler and the absentee owner who was living abroad in another Arab country who showed up with a claim "proved" with papers.
If you like the truth there you have a piece of it.
