why was the us so willing to fight this war, despite the cost?
it would provide the us a large amount of money if they won
it would show the us commitment to the truman doctrine and their promise to contain the spread of communism
the us would gain rights to the natural resources in north korea if they won
the korean people would feed the americans

Explanation:

The Korean War was part of the US's Cold War strategy to contain communism. The Truman Doctrine committed the US to supporting nations resisting communist expansion. Fighting in Korea showed this commitment. Other options are incorrect: there was no major financial gain from winning, North Korea’s resources weren’t a US goal, and feeding Americans wasn’t a war motive.

Answer:

It would show the US' commitment to the Truman Doctrine and their promise to contain the spread of Communism
