U.S. As a World Power The United States became a world power between 1890 and 1974 through the winning of World Wars and through economic growth and stability. By 1890, the U.S. economy was the best in the world, and American industry was producing double what Britain was. During that time, though, the U.S. was not strong militaristically or diplomatically, as these were areas on which it needed to work.

The development of the military during that time was valuable, though, because it meant that the U.S. was able to be much more prepared for World War II.

Second, the military was made strong and long-lasting, so it could withstand future problems. Third, other countries realized they could count on the United States for humanitarian issues and to stand with them when needed.
If the Axis Powers had won the war, however, things would have likely been very different. Nazi Germany would have continued down Hitler's path of exterminating the Jewish people, and that would have likely spread to other countries -- and potentially to other races, origins, and religions. The United States would not have the power it…
