Gorbachev was the leader of a narrow group of people that climbed the political ladder to destroy the USSR from inside. First, he replaced most of the real communists for people who were against the USSR and incompetent. This neutralized most of communist's activities. You see, political activities into the USSR were done via institutions. By replacing their leaders, he shut most of them down. Those who broke up with these reformists led institutions were either dealt with with KGB or cut in to work under Gorbachev too. The biggest infight was inside the KGB, as they were fierce communists that understood Andropov's reforms.
Many of its reforms were then sabotaged from the inside by himself. For example, acceleration was the idea to make some industries have a 3rd shift: but then, Gorbachev didn't allow to send buses, kitchen personel, provide extra electricity, etc. So, it was a disaster economically - which was his objective. He would then blame communists and communism again and again, while using the media against communism and replacing the normal curriculum with a pro-capitalist one.
He then faked the so called August Coup, which was never led by hardliners but by his own reformist cabinet. Soldiers were sent without weapons, people were brought there by buses sent by the communist party itself. They were behind it all, and its well documented.
By this time he and Yeltsin were acting as a scissor: Gorbachev faked being a communist, and did nothing when Yeltsin banished the Communist party. The Red Army was humiliated and Gorbachev took care it wouldn't do anything to stop the collapse of the Union.
When the other republics still didn't leave the USSR, he forced them out and then declared the dissolution of the country. When people marched into the streets to stop the dissolution of the country, Yeltsin then got help from the CIA and the Bratva in Russia and killed thousands on the streets.
