I would be happy if Putin used everything in the Russian arsenal on these barbaric monsters.
Not necessary. All they need is a lot of rope. Start hanging young chechyn men. Yes. Reprisals. One per hour or one per 5 minutes. Leave them hanging in the public square until nice and stinky. Preferably rebels, but it doesn't really matter. Someone has to die for these children.
Or use bullets and stack them like cordwood. It doesn't really matter. As long as Chechnya (and the rest of the world) learns the lesson. SOMEONE HAS TO GET TOUGH. SOMEONE HAS TO UNDERSTAND THAT THERE ARE NO RULES!!!!! (/savage rant)
