Putin is surrounded by his own praetorian guard who are personally beholden and extremely loyal to him. Their fortunes rise and fall with Putin. I believe that just about the only thing that would cause them to turn on him in any way, would be if he were to try to pull the nuclear trigger. Even so, all of their families are guaranteed a place in one of the Russian deep, nuke proof shelters. Very low order of probability that his praetorians will allow an assassin to get to him or allow a coup.
