if Putin is very & terminally ill, why haven't the oligarchs toppled him & replaced him with a different hard man or puppet? Terminally ill people are too tired to be effective despots or protect the oligarchs' interests.
Doesn't have whiff of credibility.
Putin's always been a rampant fidgeter. He's always had this weird gait thing (how he walks) where he manages his right hand as thought he's ready to reach for a gun (prompting comments he was KGB trained). He was accused of gasping for breath when he was merely trying to be emotional (soldiers' mums). He shakes his hands and breathes funny when being emotional (always has done). He has, if you watch enough videos (go back 20 years to do this), a pretty good "common touch" with people. By showing emotion in these ways.
btw, there's a clip somewhere of Putin singing Blueberry Hill in English. Worth watching because funny. His English accent is awful.
