All your statements are very ignorant. Let me educate you:
1. When Spain expelled the Jews in 1492 and Portugal in 1496, this Jews moved to Turkey, Tunisia, Algeria, Morocco, Egypt, where they remained for 500 years! Such is your gratefulness.
2. The Ashkenazi are facing humiliation these days because their DNA has been confirmed to be 100% European and therefore 100% alien to the Middle East. They have no goddamn right to remain in Palestine except as visiting tourists.
3. The Jews did extremely well in Spain when it was under Muslim rule than they had ever done before that.
