In the words of Azzam Pasha, the then secretary of the Arab League "This will be a war of extermination and a momentous massacre which will be spoken of the like of the Mongolian massacres and the Crusades". They therfore urged all Arabs to flee temporarily, and then reclaim their homes after all the Jews were killed. When their plan failed, and created a million refugees, not one Arab country was willing to help their fellow Arabs, and they callously left them in their refugee camps. When more than 1,000,000 Jews were expelled from the Arab countries (something that those who speak of the "Nakhba" always neglect to mention) they were welcomed into Israel, and today there are no Jews in refugee camps.
