The economy of the non-gas/oil exporting countries of the Arab world is larger or of similar size to the economy of Turkey, Iran and Israel combined. To compare those countries with the entire Arab world is moronic. Let me remind you of the fact that the GCC alone has a bigger economy than all 3 countries combined. There is a gap today but that gap won't exist in the future. Simple demographics will ensure that. Look at the rise of other hugely populated regions and countries. Where was China 60 years ago or India? Much worse off than the current status quo in the Arab world.
As for dominating, no regional power is able or going to dominate any single Arab country that is not divided in itself (locals divided) or at war. Once Iraq stabilizes for instance no regional power is going to dominate them.
Arabs are already the strongest on most fronts despite being in one of our worst moments in history so think about what it will be once things will improve which they will coupled with the demographics and future economic prognosis and an almost unlimited talent pool of people who only need the right structure and environment to flourish in.
Regional anti-Arabs will be miserable for a long time in the future. Let them "enjoy" the few conflicts currently while our numbers grow while theirs decrease in comparison and while our economies improve and grow despite being at our worst and despite all obstacles which are not comparable in any of those 3 countries. One of which is tiny Israel which is 50% Arab already ethnically already as 21% of the population is Palestinian Arab and around 66% of all Israeli Jews being Arab Jews originally from Arab countries.
Anyway this source is Jewish. Of course most of the Arab Jewish lot is a bunch of self-hating individuals trying to prove their "Jewishness" by being anti-Arab due to the Palestinian conflict.
