I'm not sure we get very far by examining the political conflicts in each Arab country.
Agree, in part. But each country is different from one another, so shouldn't necessarily all be lumped together into the same pot.
Note, Iran is not a Arab country.
It is the percentage in each of those segments that differentiate one Arab country from another and these percentages are in a state of change or flux as Western values and lifestyle become, for better or worse, more influential (accelerated in the last decade by the internet).
Very good points, but its the increasing influence of Western couture (which the internet is helped to spread) that has in part fuelled many of the problems in the Middle East as more traditional, Conservative types become more entrenched in their views which leads some to extremism.
I think the only hope for the Middle East is the growth of segment (a). More trade between the Middle East and the West, with more cultural exchange and less political or military interference, will encourage the growth of segment (a) and the gradual diminishment of segments (b) and (c). Segment (d) will die out naturally. Segment (e) is presently neutral-relatively harmless but might need to plan for the day when oil become less needed.
I fully agree with your hope there, but it is just that - hope. It could go the other way with more people turning to hard-line old fashioned views as they see the spread of liberal Western culture amongst their midst and wish to eradicate it.
