We can give Gorby some credit for reforms in the former Soviet Union. In the end, the process and the desires of the people for changes led to the dissolution of the Soviet Union.
On the other hand, Gorby didn’t want to see the Soviet Union disappear. He wanted to reform communism, not see it done away with.
I’m not sure he has anything to add to debates about issues in the western world or needs for reform that he thinks we need.
His recipe is for the West (namely the US) to become more Red.
