I honestly believe that Putin is deranged and is potentially a genuine danger to world peace. I believe that our best policy is to make life as difficult as possible for the ordinary Russian people and that Putin's problems come from within. We have to hit them as hard as possible through economic, social, sporting etc. sanctions which makes life as unpleasant as possible for them. They have been fed lies by Putin and if life is made difficult because of these lies then perhaps they could turn on him. The biggest worry is that this is a mirror image of 1939, Hitler and the situation in Czekoslovakia.
