If the west hadn’t supported Yeltsin overthrowing Gobachev, Russia would now probably a lot more stable and democratic.
This is absolute pish, of course.
The west didn’t support Yeltsin’s overthrow of Gorbachev, not least because Gorbachev wasn’t overthrown by Yeltsin. Gorbachev was arrested by a rightist anti-Yeltsin clique led by Kryuchkov etc. Yeltsin’s defense of the White House in 1991 was a defensive attempt to stop the RSFSR Supreme Soviet being dissolved by the putsch committee, not an anti-Gorbachev coup. Prior to the August coup, the SU was still seen as being viable within a looser constitutional framework, a project in which Yeltsin and Gorbachev were (uneasy) partners – the various republican leaders only really spiked the SU in December 1991 in Minsk.

Not only did the West not precipitate the August 1991 coup and the dissolution of the USSR, it also entirely failed to predict, recognize and plan for it. It was a monumental intelligence and analytical failure.
3)
There is nothing to suggest that Russia would be more democratic and stable if August 1991 hadn’t happened. Gorbachev was fantastically unpopular and would never have clung to power. By 1990, there were already conflicts in Nagorno-Karabakh, pogroms in Sumgait; civil disorder in Kazakhstan, and determined elected independence movements in the Baltic states. Gorbachev himself was no democrat, having ordered the suppression of democracy movements by military means in Riga and Baku, and – you know – being the principal of a failing totalitarian regime.
