Did the yalta agreement establish the united nation and the NATO?

The Yalta Agreement, reached in February 1945, primarily focused on post-World War II Europe and the reorganization of territories. While it laid the groundwork for international cooperation, it did not establish the United Nations or NATO. The United Nations was officially founded in October 1945, after the war, while NATO was formed in 1949 as a military alliance in response to evolving geopolitical tensions.
