Answer:
There were many significant changes brought about by World War II that have had a lasting impact on the world, but perhaps the biggest impact was the emergence of the United States and the Soviet Union as the two dominant superpowers in the world. This marked a major shift in the balance of global power, and it set the stage for the Cold War, which lasted for several decades and shaped many aspects of global politics and international relations.
The United States emerged from World War II as the world's leading economic and military power, and it played a major role in the rebuilding of Europe and the establishment of a new global order through institutions like the United Nations. Meanwhile, the Soviet Union became a major superpower in its own right, with a large and powerful military, and it played a leading role in the spread of communism around the world.
The rivalry between the United States and the Soviet Union shaped many of the major events of the post-war period, including the Korean War, the Vietnam War, and the arms race, among others. This rivalry also had major implications for the developing world, as the two superpowers competed for influence and control in various regions.
Overall, the emergence of the United States and the Soviet Union as the two dominant superpowers of the post-war world had a profound and lasting impact on global politics and international relations, and it continues to shape many aspects of our world today.
