Communism is an idea which cant be stopped with bombs and bullets. Communism as an idea has long since been discredited. It was Soviet power. and not ideas. which swept over East and Central Europe. The Berlin Wall was built to keep people with ideas from going west. The invasions of South Korea and South Vietnam were military actions. No elections brought Ho. Mao. or Fidel to power. Brezhnev. Kadar. Husak and Ulbright are afraid of their own people. and try to block ideas from the West by jamming their radio broadcasts. Look at the refugee movements out of East Germany. Hungary. Cuba. the Peoples Republic of China.
