There was no ‘victory’.
The fall of the Berlin Wall and subsequent events were merely the kicking of the communists bees nest to let them swarm all over the world, especially the United States to wreak the havoc of communism on America.
Gorbachev was GIVEN a piece of the San Francisco Presidio for his home base (ironic or premeditated?). He established Green Cross International for the theft of water rights in the US and preceded to corrupt municipal governments into selling water rights to foreign entities.
He has participated in many global government initiatives and walks a free man in spite of his treasons against the US since taking residence here.
I am personally convinced that the fall of the Berlin Wall was solely to send communists out from Russia where they had been contained the whole cold war, out in to the free world to destroy it.
Evidence of this is identified in the current occupant of the white house.
