Earlier quoted context omitted.
They moved there after hundreds of years of not living there. It was homeland of someone else and they made it their own. But the process was not friendly. Anti-semitism in those other places was also very real .. but the homeland itself was a new place for massive amount of those people and peoples got pushed out.
That's a rewriting of history. There were always Jews there, and they didn't push anyone out - the land was very sparsely inhabited. The incoming Jews bought land like anyone would when they move someplace. The Arabs responded with massacres, instead of just living near their new neighbors. If they had not done that history would be quite different.
Whiel there were always some Jews, most of the Jews living there moved there after 1900, as many of the surrounding Kingdoms (particularly Egypt and Saudi Arabia) had become increasingly antisemitic and forced them out. Israel's current location wasn't even the only place considered, they also looked at a place in Africa, and this was possible because most people were immigrating there and it wasn't a generational homeland.
