If Yeltsin hadn't been a drunk, it's possible that Russia would be more like the Poland of 2022 than the Russia of 2022. I still believe that being open with Russia was the right strategy even if it has blown up spectacularly in our face.
At the end, Yeltsin was just the face of KGB/FSB regime, and later directly abdicated power to it's representative, who bombed buildings in Moscow to get elected.
Actually Yeltsin abolished the elected parliament in Russia in 1993, and then had the army bomb the parliament. This was done openly and celebrated by President Clinton, the US Congress and the US press. The US put all its weight behind removing power from democratic elections and a parliament as it wanted to consolidate power under the Russian army and president (now Putin).
This was FSB deciding what army does 101.
