Answer:
C . The United States considered the war a success for containment while the Soviet Union considered it proof of its own status as a world power.
Explanation:
Even though the U.N. armed forces led by the U.S. military had averted the complete occupation of South Korea by the North Korean army and came very close to occupy the whole Korean peninsula thus allowing the creation of a unified Korean state under the government of Seoul, the Chinese intervention in November 1950 threatened to drive the U.N. forces out of Korea. After a counteroffensive by the U.N. forces, the opposing forces reached an impasse pretty much along the borderline prior to the war, and no significant territorial gains were made by either side since the second half of 1952 until the end of the war.
Though a partial failure, the U.S. announced the outcome of the Korean War as a triumph of contention against communism. The Soviets, in turn, claimed a victory of communism against capitalism as the U.S. and its allies had been driven out of North Korea.
