Answer:
the United Nations.
Step-by-step explanation:
The War of Corease took place between 1950 and 1953. Its components were the Republic of Korea (or South Korea), supported by the armed forces of several countries commanded by the United States; and the Democratic People's Republic of Korea (or North Korea), supported by the People's Republic of China and the Soviet Union. The war was one of the earliest episodes of the Cold War. Excluding more than 3 million civilians and almost 15% of the population of the dead North, it constitutes one of the most bloodthirsty wars in history.
The participation of the United Nations (UN) in the war materialized with several resolutions of the Security Council of the United Nations in favor of South Korea, endorsing even the use of armed force. The legitimacy of United Nations resolutions on the occasion of the Korean War was questioned by the Soviet Union and other states not aligned with the United States, which supported Chinese intervention.
