This politically-debilitating belief-tendency is almost universal in the Gulf and Levant. Revisionism starts early there.
Most people (if you look at whole populations) think that forces are at work which are hidden from them. The question, most of the time, is only how incredible the conclusions are.

Egyptians are rather more realistic.
