I realise that my personal experience of working (1990s) in Russia are probably not statistically significant (with a population of approx 140million, I met, perhaps c100). I found the. Russians I met seemed to recognise they had been conned by their government (of course, I had a similar experience of realising that perhaps, our Government had not been entirely truthful). The difference I noted was that they (the Russians) seemed recognise that they could do little to change things, where-as I continue to think we possibly can (perhaps I am over optimistic).
However, I do agree, the chances of bringing Putin to trial, for what he has done, are pretty slim. That doesn't mean we should not seek to bring charges against him, and, generally, make life as difficult as possible for him (IMHO).
