5. The Korean War was considered to be a part of the US foreign policy known as "containment". Based on this
timeline, how did the US participation in the Korean War exemplify the U. S. foreign policy of containment?

America used the Military.

Explanation:

Here's America's Foreign Policy to help you understand: Military, Foreign Aid, and Treaties. As you can see above, the U.S. used the military to deal with a foreign country, as the american foreign policy states they should use only if absolutely necessary. As North Korea was trying to take over another country (South Korea) at the time, The U.N. (United Nations) immediately sent in over 20 countries with 90% of their military in, as taking over other countries is genuinely one of the greatest offenses in the world today.
