Prediction:
Putin is a coward, ( you may remember I sent him a white feather 3 months ago) He is only 'strong' when he is in a position of safety. The attacks today on civilians are as far as he dare go, though he would continue to order escalation if he had a sufficient supply of weapons, which I don't think he has. Going further than this, his only option would be nuclear, which he won't do because he hasn't the balls & it would put his autocratic control in jeopardy which is the only thing he really cares about.
He is fighting a war he cannot win & knows it. What he will do, rather than face the humiliation of defeat & after blaming everyone else but himself for this, one of the greatest military blunders in world history, being too cowardly to take the bottle of vodka & revolver exit, is to step down & appoint some stooge as his successor in the hope that he will somehow be able to slip away & avoid retribution from the civilized world.
