There is only one way to win a fight with an enemy of this type, and unfortunately, it requires the commission of what are currently considered "war crimes". For example, the Russians could destroy a town of 10,000 Chechens. They could then say, for each child you kill, we will kill 1,000 Chechens. If you kill all these children, then there won't be any more Chechens, and then we will sell plots in Chechnya to Russian settlers, and make a big memorial to all the children. That's how you win. I don't know how you live with yourself after, but that's how you keep from being slaughtered by Muslims who don't respect anything civilized. Perhaps after you win, you can restore civilized rules. You have to be willing to respond in kind to what they are doing, or they have the advantage. I think there should be an exception to war crime law, that says that if you are responding to war crimes committed against you, and are required to do so in order to win the war, then you can commit atrocities as a response.
The British understood this when they firebombed Dresden. It was near the end of the war, and it was a message to the Germans--"don't ever pull this s*&t again!" It was probably a war crime, but it was also probably justified.

Terrorists can't function without support from the people around them. Ask any WW2 vet, they didn't give a crap about the people of Germany or Japan. They started the war and our guys finished it.
I hope the people around this school burn down all of the mosques in their city. Then kill or run the Muslimes out of town. We *need* some mob violence in Russia and the West against the slimes. It'll be ugly but it needs to be done.
