Putin has ultimate trump card if he can launch on his sayso alone. back in the Soviet times the Central Committee would
have the defacto power to release nukes. Now there’s just the lapdog State Duma. Putin can decide he’s is toasted at us and give a launch order? That’s a scary thought, and we had better be damned careful poking sticks at him.
The real danger is that Putin might start a nuclear exchange by accident. I have to assume that there are other people who have taken steps to make sure that these things won't happen by accident. Of course, I would have thought that there were people around him to make sure he didn't accidentally cause the death of hundreds of innocent airline passengers, but apparently there was no one there to protect him and the rest of us from his incompetence in that regard.
So, who knows? His clumsiness may kill us all.
