Why did the United States take part in the Korean War? A, To establish a colony on the Korean Peninsula
B, to defend South Korea against communist aggression
C, to aid its Chinese allies against an aggressive neighbor
D, to prevent North Korea from acquiring nuclear weapons

B

Explanation:

It certainly wasn't C and D, however critics of US foreign policy would possibly cite A. I would argue in the context of the question it is definitely B.

this is not a question its simply asking you to read and write a few sentences and   the question on the bottom its fairly easy, you can do this!
