The Collapse of Communism

the reason for the collapse of the berlin wall was that people left countrys without exiting visas and caused a migration to east germany. countries formed a union against communism called the warsaw pact. Which denied communism into countries. communist parties still stayed political. traditional communist partys with dictators china cuba north korea and others. also chinese parties crushed their schools. The U.S. was able to profit from its imperialist exploitation of other countries while socialism could only lose economically in that competition.
