The desire for story is very, very deep in human beings. We are the only creature in the world that does this; we are the only creature that tells stories, and sometimes those are true stories and sometimes those are made up stories. Then there are the larger stories, the grand narratives that we live in, which are things like nation and family and clan and so on. Those stories are considered to be treated reverentially. They need to be part of the way in which we conduct the discourse of our lives and to prevent people from doing something very damaging to human nature.
The political elite in Russia don't want domestic reform, they aren't ready for it. As such, they welcome an external threat. You have to remember that Russia rests on two national concepts: defense and sovereignty. We approach the question of security much more reverentially than other countries do.
