Putin isn’t sleeping well... He knows full well that the best way for this to come to an end, is for him to come to an end... Most Russians aren’t interested invading any country... They are interested in consumer goods, and all the luxury that they now have because of Capitalism... Not Communism. Putin longs for the old days... Most Russians want to forget the old days.
To win wars... You need support from your own people... A few more Russian transport planes full of troops going down over the Ukraine, and Putin may find himself the victim of a bloody coup with his head on a pike.
