What notable action did Truman take regarding post-war Germany?

The notable action taken by Truman regarding post-war Germany was the division of the country into zones of occupation. This decision stemmed from the Allied powers' need to manage the aftermath of World War II and to address the issues of preventing future conflicts. The division was agreed upon during conferences such as Yalta and Potsdam, where leaders from the United States, the United Kingdom, and the Soviet Union discussed the post-war order. As a result, Germany was divided into four occupation zones: American, British, French, and Soviet. This fragmentation laid the groundwork for the later division of Germany into East and West, further deepening the ideological conflict of the Cold War. The establishment of these zones was crucial for managing the political and economic reconstruction of Germany after the war.
