OK compare like with like take one Arab country of your choice how many wars has it been involved in since the second world war, and then ask is that more or less than your own country which I think is Britain?
There are no tribes in Europe are there? Ever been to Glasgow, let alone Northern Ireland. Is Bosnia in the Middle East? Is Rome? Is North eastern Europe. I know Welsh people who are still outraged by the Anglo-Saxon invasion of Britain.
The middle east is a big area, bigger than Europe, If now you seem to want to add Africa to that area then of course, You will find what ever you want to find.
However take a given amount of one people and a same amount of different people you will find the 'Nutter ratio' very similar.
