The statement that most objectively describes the cause of the Cold War is:
"The Cold War evolved as the USSR and Western allies deployed their own strategies and policies to rebuild the post-war world according to their own needs and values."
This statement recognizes the complex interplay of geopolitical strategies, ideological differences, and the actions taken by both the United States and the Soviet Union in the aftermath of World War II. It reflects the broader context of the time, where both superpowers sought to promote their respective systems—capitalism in the West and communism in the East—leading to significant tensions and conflicts that characterized the Cold War era.
