What were the major post war initiatives?

Major post-war initiatives after World War II included the establishment of the United Nations in 1945 to promote international cooperation and prevent future conflicts. The Marshall Plan was launched in 1948 to aid the reconstruction of European economies, fostering recovery and stability. Additionally, the formation of NATO in 1949 aimed to provide collective security against potential threats, particularly from the Soviet Union. These initiatives collectively aimed to create a more stable and cooperative global environment.
