Absolute bullshit. Arabs are not native to the region, they invaded and colonized:
Nobody is displacing Palestinian Arabs. They were given their own territory. The current conflict is because they attacked Israel yet again.
If anyone was displaced in modern history it was the Jews. Why was that, Sooly? Arabs kicked them out. Again. In the 20th Century.
Why is Lebanon an Arab country Sooly?
"The most modern Arab country" what does that mean? The most civilized? Why are Arab countries not civilized?
