"Ethnically speaking, Iraq is mostly Arab, though there are large numbers of Kurds (who are descended from Europeans), as well as Turkoman (from Turkey) and Persians..."

Bullshit. Kurds descended from the Europeans? The Kurds are ethnically Aryan, as are the Persians. Several thousand years ago, a group of the Aryans left Iran and colonized Germany, and subsequently spread throughout Europe.

This author is apparently rather ignorant of these things...
