It depends on the grievance

Part of the widely quoted John Oliver commentary on the Paris attacks (Vox) --

"Nothing about what these assholes are trying to do is going to work" Oliver said. "France is going to endure. And I'll tell you why: If you're in a war of culture and lifestyle with France, good f*cking luck."

That logic depends on convincing most people that the French culture and lifestyle which they can see up close or on television is actually attainable. If you think you're always going to be on the outside looking in, and mix that emotion with the Islamist cocktail, a different set of options can persist for a long time.
