I'm specifically referring to that quote from the Chechen rebel saying they have their hands full fighting Russia and don't have a particular beef with the US. And furthermore, it would appear that our Boston bombing "jihadist" may have been motivated by something far more prosaic than religious fervor:
The cocksure fighter, a flamboyant dresser partial to white fur and snakeskin, had been looking forward to redeeming the loss he suffered the previous year in the first round, when the judges awarded his opponent the decision, drawing boos from spectators who considered Mr. Tsarnaev dominant. From one year to the next, though, the tournament rules had changed, disqualifying legal permanent residents — not only Mr. Tsarnaev, who was Soviet-born of Chechen and Dagestani heritage, but several other New England contenders, too. His aspirations frustrated, he dropped out of boxing competition entirely, and his life veered in a completely different direction.
Who knows what makes a homicidal maniac tick. But to even speculate that this was the opening gambit some sort of expansion in the Great GWOT is just stupid. The Chechens have their own superpower to hate.
