12 dead is in no way near to war. From a plethora of potential regions to reference [CAR, San Pedro Sula in Honduras, Myanmar, Sonora and Chihuahua in Mexico, Nigeria, Mali, Chad, Niger, Libya, Punjabi region, Western Province of Pakistan, Colombia] i am surprised you picked Paris.
Regardless, you make my point: everything is cool until it is not. So who stands to gain by making shit fall apart?
My money is on a country overstocked with weapon systems, an abundance of ultra nationalists, and a near mono-economy.
