None of us can predict what Putin is going to do, probably not even Putin. It just seems very likely that everyone else around him must now be questioning the faith that they put in him in the past. He is an angry, desperate man.
US view of Putin: Angry, frustrated, likely to escalate war
If Putin were a strong leader or a courageous man, he wouldn't be sitting at the end of a mile-long table in every meeting and spreading that bizarre image all over the news media. It is prudent for him to be fearful, but not to show his fear. He may like to threaten that he's going to push the nuclear button, but would a man who is afraid to let anyone near him really be the one to start a nuclear war? Anyway, this ex-KGB agent thinks that Putin, like Trump, is just one of those leaders who thinks he is always the smartest person in the room. So he has dug himself into a very deep hole.
