Question

tensions between britain and germany
tensions between japan and china
tensions between the u.s. and ussr

Explanation:

After World War II (1945), the global geopolitical landscape was dominated by the Cold War between the U.S. and USSR. This ideological, political, and military rivalry (tensions) had far - reaching global impacts. It led to proxy wars (e.g., Korean War, Vietnam War) around the world, arms race (nuclear arms build - up), and a bipolar world order. Tensions between Britain and Germany were mainly significant before and during World War II. Tensions between Japan and China, while important in the Asian context, did not have the same global - scale impact as the U.S. - USSR tensions during the given period.

Answer:

tensions between the U.S. and USSR
