When eastern Aleppo fell to rebel factions in 2012, well-organized radical Islamic preachers from abroad quickly moved in and began proselytizing extremist views to the local population. It is an example of methodically planned Islamist radicalization in the chaos and turmoil of war. And it raises fears that the effects of this extremist phase in Syria's civil war will linger for years to come.

In some ways the Syrian civil war resembles a proxy chess match between supporters of the Bashar al-Assad regime— Iran, Iraq, Russia and China—and its opponents— Turkey, the oil monarchies, the U.S., Britain and France. But the current conflict only resembles chess if the game is played with multiple sides, backstabbing allies, and conflicting agendas.
