Classify the actions taken by the United States during the Korean War into the appropriate categories: military intervention, diplomatic efforts, humanitarian aid, and propaganda. Which category best describes the U.S. decision to engage militarily against North Korea?

During the Korean War the United States carried out four main types of actions: it sent troops and fought on the battlefield, which is military intervention; it worked with the United Nations and allied governments, which is diplomatic effort; it supplied food, medicine, and shelter to civilians, which is humanitarian aid; and it broadcast anti‑communist messages to influence public opinion, which is propaganda. The U. S. decision to send soldiers and aircraft into Korea against North Korean forces is an example of military intervention. This action is distinct from diplomacy, aid, or propaganda because it involves direct armed engagement.
