Congratulations, you can cut and paste from wikipedia.
The Ottoman Empire ceased to exist. They chose the losing side of WW1. The aftermath of WW1 is what set the stage for the rise of Nazisim in Germany and arbitrary borders in the Middle East that set the stage for numerous subsequent wars, with a touch of Cold War meddling.
Europe didn’t want the Jews, and did a pretty good job of nearly exterminating them. Not just the Nazis, but also the Russians, with even the Allied powers initially serving as enablers. You can’t blame Jews for wanting a homogenous nation to call their own, and for a variety of reasons, their Biblical homeland became the center of gravity.
The British and Arab world is who screwed over the Palestinians, not the Jews.
I don’t blame the Palestinians for not wanting to accept the new world order. But like the Confederacy, they chose civil war and violence. There are consequences.
