Moza: although you make some valid points there, i'm just going to repeat my eariler post to you.
We as generations of present time we can only observe the impact and amount of neglect caused by recent colonies.
now coming to the second part of your comment regarding the Jewish state which the Arab invaded. I think you have made a great mistake by not attending your history classes becuase when the armies went in to Palestine it was ruled by the Romans not the Jewish and the armies who went in to Palestine were people of from allmixes of racial background they had the Yemenites, The Egyptians, The people from past kingdoms of Jordan and Tabuk.
So it wasn't really only Arabs.
