The truck driver of Nice was a drinker, a small-time crook prone to mental health issues, and going through a nasty divorce. He was not was an observant Muslim, yet there is always the possibility that he found the final reason to go on a rampage on some extremist web site. ISIL has claimed him as “a soldier of the Islamic state,” but there’s no evidence to support that. He was a disturbed individual who carried out a terrifying act, but does that make him a terrorist? No one knows, just like no one knows how you fight that war.
