Containment of communism
Did it work?
Mao didn't only change china through communism but also used powerful government forces to change culture. He didn't want the people focusing on past traditions but to focus and celebrate new communistic customs.
Korean and Vietnam War
Korean war ended with it dividing at the 38th parallel, Vietnam war ended with Vietnam dividing at 17th parallel. In both north consisted of communism government and south non communism.
Did it or did it not?
In my opinion, i think containment did work because U.S tried to keep communism in one area which did happen
