Jews were first in Israel and controlled it for ~1000 years. Then they got replaced by Arabs and then they got their land back. To tie it back to your analogy - it works in the opposite way. The modern state of Israel is comparable to the Reconquista. Also from an outsider's pragmatic view I'm very glad that there's a non-Arab power in the Middle East. We'd get 100 terrorist attacks every day in Europe if the towelheads weren't preoccupied with their conflicts with Jews.
