Peaceful??

No. The attacks were normal, not news. Think Jim Crow.

And the "Nakba" is mostly illusion. Lots of Arabs left at Arab behest, getting out of the way of the intended destruction of Israel. Oops, didn't work. Israel didn't ethnically cleanse Israel, most of it's neighbors did ethnically cleanse their areas.

And where you go wrong is thinking it was forceful. They bought land and moved to it.

And the root cause is that the Jews threw off centuries of oppression and the Muslims can't stand that. They considered the land conquered. As normal, when a victim throws off the abuser the level of violence goes way up.
