Following world war ii, how did the world’s leaders promote peace and reduce poverty?

Good Morning!
 
After World War II some efforts were made so as to maintain a state of peace. In fact, the United States and the Soviet Union fought a war we call the "Cold War", as regional conflicts continued to occur under funding from these groups. A direct confrontation between countries was, however, infrequent. The creation of the UN, investment in devastated countries (also with the intention of raising allies) and military aid were the most striking measures.

Independent executive agencies are more specialised.
