…the rise and evident success of ISIS. Take, for instance, this take on who joins the group:
But in truth, these new foreign fighters seemed to sprout from every conceivable political or economic system. They came from very poor countries (Yemen and Afghanistan) and from the wealthiest countries in the world (Norway and Qatar). Analysts who have argued that foreign fighters are created by social exclusion, poverty, or inequality should acknowledge that they emerge as much from the social democracies of Scandinavia as from monarchies (a thousand from Morocco), military states (Egypt), authoritarian democracies (Turkey), and liberal democracies (Canada). It didn’t seem to matter whether a government had freed thousands of Islamists (Iraq), or locked them up (Egypt), whether it refused to allow an Islamist party to win an election (Algeria) or allowed an Islamist party to be elected. Tunisia, which had the most successful transition from the Arab Spring to an elected Islamist government, nevertheless produced more foreign fighters than any other country.
The rest of the linked article suggests that accumulating more facts about ISIS and how it came to be will only “baffle” us as we become increasingly horrified by the phenomenon.
