Khrushchev to Brezhnev was "peaceful".
For some values of 'peaceful' I suppose. Kinda like these 'mostly peaceful' protests we're having here? Of course, another phrase to describe them would also be 'somewhat violent'.
The Russians may very well like Putin, and what he's doing and has accomplished for them. Nonetheless, I think they need more and better examples of an orderly transfer of power.
