This is wildly one-sided and basically incorrect. The Palestinians initiated multiple conflicts against the Jews, even before the foundation of Israel. The Jewish people beat them back every time, and this same pattern continued after the Israel's founding. What happened throughout history when someone beat back a hostile enemy that attacked them? The loser lost territory, resources, and freedoms.
Which isn't to say that Israel hasn't done some seriously unethical things, but this notion that the Palestinians are poor innocent victims that have never hurt a soul and carry no blame for their situation going back a century is absurd and ahistorical.
