On a principal thing, concerning oil, it should be noted that even if oil runs out, the arab nations are far from being defenseless and without influence. thanks to global economy and corporations being mad for getting listed at stockmarkets, they can spend their billions and multi-billions of dollars to buy themselves into economical keystructures of the West - and they do it, and do it deliberately and on large scale. When oil is running out we may find that we have started to work for industries that significantly are influenced or even owned by Arab clans.
Cheers!
