Mr. Bluenote: Yeltsin is a somewhat problematic figure, don't you think? His corruption and incompetence lost most of the 90s for a rebuilding Russia...perhaps a bit of conflict might have been worth freeing Russia from his dead (and inebriated) hand...
I am also not sure that I agree that absent the failed coup, there would have been a greater tendency towards violence. There has been plenty anyway, and the hardliners didn't get support from the army or the security agencies in any case. In point of fact, Putin, who was a mover in the KGB at this time, got his start in big-time politics in Russia because of his support for Yeltsin during the coup. I just don't see who (other than the hardliners, who were discredited a bit earlier, and who didn't enjoy much support anyway) would have fared much differently
Wait! I do know someone else....Gorbachev, who was exposed as a fraud and a creature of the Western media much earlier than would have been the case without Yeltsin's stand at the Kremlin...
