Question

Why did the US and UN send troops when North Korea attacked South Korea?

to create an alliance
to protect colonial interests
to follow the containment policy
to create a demilitarized zone

Answer 1

The primary reason the US and UN sent troops when North Korea attacked South Korea was **to follow the containment policy**. This policy aimed to prevent the spread of communism during the Cold War, and the invasion of South Korea by North Korea was viewed as a direct threat to that goal. The UN, with significant influence from the United States, intervened to support South Korea in an effort to stop the expansion of communist influence in Asia.
