What of these countries did the US force to adopt a democratic form of government following World War 2?

After World War II, the United States played a significant role in promoting democratic governments in several countries, particularly Japan and West Germany. In Japan, the U.S. led reforms that established a democratic constitution and government structure. Similarly, in West Germany, the U.S. helped to create a democratic political system as part of the broader effort to rebuild Europe and contain communism during the Cold War. Other nations in Europe and Asia also experienced democratic influences, but Japan and West Germany are the most notable examples.
