Foreign interventions by the United States are when the United States sends its military or money to help other countries with their issues. This usually happens when another country has a bad situation they can not solve on their own, like a war or natural disaster, and the US wants to help. The US will either send soldiers to help the other country, or send money to help the people affected by the situation. The US does this to help people in other countries and make sure their security is safe.
