Nice of you to change the subject. The reality is that all tribal people all over the world have been taken over by larger more power groups to form Countries. Right or wrong, this has been the progression of mankind.
Just for balance, over a period of approximately 30 years, Arab warriors, riding fast horses and camels, conquered the entire Persian empire and much of the Byzantine. They conquered lands included Egypt, Syria, Iran, Iraq, and much of Afghanistan and Baluchistan. Arab warriors were filled with confidence that God destined them for victory. What happened to the people refused to accept Islam? They ran away, were killed, or remained marginalized to this day.
