Which statement regarding the Korean War is NOT true?

The assertion that the U.S. military force was always adequate during the conflict is not true. Throughout the Korean War, the effectiveness and adequacy of U.S. military forces were challenged by various factors, including unpreparedness, underestimating the North Korean and Chinese forces, and changes in military strategy. The early stages of the war saw significant setbacks, with U.S. troops being pushed back to the Pusan Perimeter and facing overwhelming numbers. Additionally, the sudden entry of Chinese forces caught the U.S. military off guard, leading to further assessments of troop levels and capabilities. Consequently, the idea that the military was always adequate does not align with the complexities and challenges faced during the war, making this statement the correct choice for what is not true.
