Mikhail Gorbachev has died

The United States didn't do enough to help Russia transition to democracy in the 1990s. There was no "Marshall Plan" after the Cold War like there was after World War II. This was a huge mistake, and we see the consequences now, with Russia having turned back toward totalitarianism and imperialism. Sadly, it seems that Gorbachev's efforts were mostly for naught. But it was courageous at the time to open up the Soviet Union to glasnost and perestroika.

Of course Yeltsin was a big part of the problem too.

This wording implies an accident, or negligence. In fact, it was an intentional and explicit policy of "shock doctrine" economic deregulation and ultra-liberalisation that led to the absolute misery of the 1990s, and the kleptocracy that continues to this day.
