Interventionism (politics)

Interventionism is a type of politics where a country or group of people (like the United Nations) get involved to help solve a problem or help someone else. For example, if a country is going through a war or a disaster, interventionism can be used to send in aid and resources to help the people in that country. This may include providing food or medical supplies, or sending in soldiers to help fight in the war.
