>> when you see this turkish riot police officer, you hear what he says, he says "god is great, don't forget aleppo, don't forget syria." do you see his motorizations as a radicalized islamic terrorist or someone that is more a nationalist? it's hard to know at this point, but what is your instinct? >> turkey has the distinction of being hated by all sides in the syrian civil war. in the syrian civil war, you have kurds and isis and the assad regime, but they all fight turkey at the same time. you're seeing a government employee, whose job is to be apolitical, carry out a political murder. so this points to a very dangerous trajectory for turkey. for a very long time, turkey was known as a country of stability.
