True, the problems of muslims in France may have a lot of factors, although there is absolutely no excuse for extremism and terrorism.
But, given that many muslims move in order to seek a better life in west, perhaps involved Arabic societies are going to have to pull themselves together to try and integrate and benefit from interaction with the rest of the world; and I refer to the goal of developing and benefiting from the international economy. to some extent, small arab nations are already doing this.
From my viewing for Arabic movies and docos, most people there too want a better life for themselves and families in economic terms.
but the policy elites and people need to insist that radicals are quashed, and get over their harsh historical experience and cleavages, just as many Asian societies have. They have to define an agenda to build themselves up, say as Turkey has to some extent.
Until then, I suspect the factors you refer to will persist.
Big problem for any effort by extremists is that all major powers cannot tolerate them, China, US, France, UK, and Russia. Hopefully ideas and resources from them can aid development.
Having said this, invasion of West of Iraq was one of worst decisions ever.
