"... sometimes I think that maybe it would be best if our bear just sat still. Maybe he should stop chasing pigs and boars around the taiga but start picking berries and eating honey. Maybe then he will be left alone. But no, he won’t be! Because someone will always try to chain him up. As soon as he’s chained they will tear out his teeth and claws. In this analogy, I am referring to the power of nuclear deterrence. As soon as – God forbid – it happens and they no longer need the bear, the taiga will be taken over."
Vladimir Putin, 18 December 2014
