Indeed. It seems reasonable to postulate that a more 'unconventional' use of a nuclear weapon is the more likely scenario today. The documentary 'Count Down to Zero' discusses such scenarios (http://www.imdb.com/title/tt1572769/) at length and the impression left is somewhat terrifying. The solution? I haven't the foggiest as global disarmament seems unrealistic but the aspiration to progress beyond these ghastly devices as a global community is surely a sensible and just one.
