Interesting discussion on BBC Radio yesterday with an expert on Russian strategy. Asked about Putin threatening nukes he made the point that he has almost always included a reference into Russia's superiority in warheads in any speech on military affairs going back over 15 years - he reckoned that Putin just can't think of military without the N word coming out and secondly he HAS to mention it - other wise people might ask" what the hell did we spend all that money on".
