Jews legally migrated to the area and bought land starting 1882 driven by the rise of the Zionist movement and pogroms in Eastern Europe. If the Arabs had won the war they would have forced every last Jew out of the area and Israel would never have existed. When the Jordanian Arab Legion took control of the Jewish Quarter of the Old City of Jerusalem, the ancient synagogues were destroyed, and the entire Jewish population was expelled or taken prisoner. The same happened in the Gush Etzion bloc. If the combined Arab armies had won the war, the Jewish state would have been dismantled, and the Jewish population would have been expelled or killed.They lost but have rather pathetically refused to accept this for 78 years now.
