Decades ago as i recall, a Soviet diplomat was kidnapped in Lebanon by Islamic thugs. The Russkies grabbed a relative of the kidnappers, cut him up, and shipped the remains to the kidnappers. The diplomat was released. Violence works.
Russians have been fighting with islamic peoples for about 1,000 years. They know what to do that will gain them the respect they want. I don’t know what they have planned but, I guess lots of people are going to die.
