The US and SA. Why?
Why would any culture as ancient and a memory of thousands of years, feel threathened? A very simple question.
Go back in time, to the fundamental difference between Arab and Persian cultures. It's not that Shia-Sunni thing, although it's portrayed that way. It's a clash of ways of life. And the US, Canada, and the west have more in common with Persia than with the Arabs.
