The idea of having a state for the Jewish people is preposterous. It's ethnocentric, it's racist. Anyway, I see what you're saying.
What lead to civil war in Lebanon was Israel and the hundreds of thousands of Palestinian refugees we had to welcome, for a small country with a fragile sectarian balance, that was devastating.
Arabs are not one entity, so many Sephardic Jews were driven from Arab countries; what does this have to do with Palestinians ?
