Russia is less of a mafia State than it was in the giddy years immediately after the fall of the Wall; today, the institutions of the Russian state have clawed back much of the wealth looted by the opportunistic and independent bandits and brigands, making senior officers, officials and assorted Nomenklatura the new millionaires. Many of the original bandits and brigands remain; they saw which way the wind was blowing, and made a pact with the key state players and in return were allowed to buy their UK newspapers, football clubs and yachts without fear of death. So Russia has gone from a wild west mafia state to one of ordered institutionalised corruption. And today there is little doubt that these powerful state actors are responsible for Litvinenko's murder.
So should we bristle with righteous outrage at this most wounding of insults, the poisoning of a man as he took tea in London? Well, not, I suggest, unless we also bristle at the barbarian head-choppers of the KSA de-heading their political opponents on trumped up charges by the score. Or our NATO ally in Turkey working in league with ISIS through an open border. We don't, you understand, take positions on moral grounds - the criteria is the harm or utility to the cohort of Cameron's cronies. The savage native barbarians of the Saudi kingdom are useful cash-cows, so they are never openly criticised, however heinous their savagery.
So any criticism of Russia you hear today from Cameron or his chums will have little to do with Litvinenko and much more to do with their frustration at their failure to elbow Putin out of the middle east for commercial reasons. It's all just a game they play, in which money is infinitely more important than human life.
