Have you looked at the map of the Middle East lately?
Indeed I have. Since the Arabs have actively attempted to destroy Israel, this is what has happened.
They are involved in most of the wars in the world at this time. Misery.
They have one of the lowest literacy rates in the world.
Their average income is about 1500 per year. (roughly)
The average income for the Saudi populace has continued to deteriorate.
The Saudis are now involved in a war for their oil fields. The antagonist is Iran which supports the rebels in Yemeni/Saudi border.
Just a very short list......
