Arabs are a desert people.
The peoples, and states, of the Middle East have been more or less at war for hundreds, perhaps thousands, of years.
Good guys have light skin and speak English without accents.
Bad guys have beards and large, bulbous noses, sinister eyes and heavy accents, and wield swords constantly.
Most people in the [Arabian] Peninsula are not nomads, but are either agricultural labourers (Yemen, Oman) or inhabitants of the eight or so major maritime and cosmopolitan cities that mark the coast of the Peninsula, from Kuwait City in the northeast via Manama, Dubai, Muscat, Mukalla, Aden and Hodeida to Jeddah in the southeast.
In modern times the Middle East has been no more riven by war than other parts of the world such as Africa and East Asia, and, in the past century, much less than its neighbouring continent to the northeast, Europe. For all the wars between the Ottomans and Safavids (later Qajars), the two empires coexisted reasonably well for four centuries (1500-1914). In the period since 1945 there have been five Arab-Israeli wars but these, while catastrophic for the Palestinians, have been confined in time and space. Only the Iran-Iraq war of 1980-8 escaped external and regional state control and involved, by modern standards, high levels of casualties. Peoples of the Middle East have historically been busy doing things other than warring, like inventing algebra for instance.
Good guys can look like anyone. Bad guys can look like anyone.
