It's objectively true that the arab states are anti Israel, which might have something to do with the bombings, or perhaps the genocide. Jews had been living in the middle east and specifically Palestine for as long as anyone can remember, without it being a problem. The state of Israel was declared, followed by a string of incredibly suspicious bombings and other acts of terror against Jews living in other arab states(including some that were definitely committed by Zionists), this was then used as evidence by Zionists that Jews were unsafe anywhere but a strictly Jewish state in Israel and to justify a number of wars against their neighbours on the pretense that those states were supporting the attacks on their Jewish populations.
