I Stalin created satellite Communist states in Eastern Europe. The Chinese Communists (see CHINA), who triumphed in 1949, aided movements in Southeast Asia. U.S. opposition to these and other actions by Soviet, Chinese, and other Commmunists led to the COLD WAR, KOREAN WAR, VIETNAM WAR, and proxy wars elsewhere, particularly in Latin America and Africa. Economic difficulties, particularly shortages of food and other consumer goods, and the resurgence of NATIONALISM led to demands for reform and internal problems in Hungary (1956), Czechoslovakia (1968), and Poland (1956, 1981), and other Communist countries, and to the often violent suppression of protest.

By the early 1990s traditional Communist party dictatorships held power only in China, Cuba, Laos, North Korea, and Vietnam. China, Laos, Vietnam, and, to a lesser degree, Cuba have reduced state control of the economy in order to stimulate growth.

They are what Daniel Chirot dubbed 'tyrannies of certitude'.A particular group of people has been responsible for blocking the happy developme...
