Final answer:
Truman eased tensions and prepared for the future by replacing MacArthur, focusing on civil rights, and issuing Executive Orders.
Step-by-step explanation:
To ease tensions and prepare for the future, Truman took several steps. First, he allowed General MacArthur to enjoy the praise for his military leadership, even though he later explained his decision to replace him with Ridgeway. Truman's argument demonstrated the wisdom of limited war and was supported by Congress. Second, Truman focused on civil rights issues and issued Executive Orders guaranteeing fair employment practices and equal treatment in the armed forces. These steps helped to ease tensions and pave the way for a better future.
