@Walter Hinteler,
I'm going to take a wild guess here... I'm guessing that Russians have taken a hard look at what has happened with Milosevic, Khadaffi, and a number of other national leaders in the world as well as the Soros/Nuland/Obunga.US-neocon-deep-state overthrow of the government of Ukraine and numerous similar activities and then the situation which they saved in Syria, and determined that having those kinds of capabilities are, unfortunately, necessary to prevent their being fucked with in our present world.
