[Cronos]

I would add in that not all the people we call "arabs" are really "Arabs". The Berbers from Morocco to libya are nearly 100% descendents of the Imazhigen, albeit arabized. Egyptians are still, mostly coptic /ancient Egyptian in origin. Sudanese, the same. Even amongst the Semitic peoples, the Syrians are of Aram, the Lebanese of Phoenicia/Canaan, the Iraqis are Assyrians/Iranis/Kurds(aka Medes) and the Yemenis are South Semitic peoples. the only true "Arabs" are from the Najaf.

The Nabateans, like the Amorites before them were a Semitic people from the Arabian peninsula, but not the Bedouins (who are the true Arabies).

[G8 Diplomat]

the Iraqis are Assyrians/Iranis/Kurds(aka Medes)

Modern Iraq is 80% Arab; the rest are Assyrians, Kurds, Chaldeans, Turkomen, etc. Of course, the only reason the Arabs got there is by conquest. They were not native to the region that is now Iraq.
