Final answer:
The differences in American contributions between WWI and WWII are profound, with the U.S. transitioning from a late participant in WWI to an economic and military superpower by the end of WWII. This transition was marked by significant economic growth, an overwhelming military force, and an elevated global influence post-WWII.
Explanation:
The American contributions to World War I (WWI) and World War II (WWII) had significant differences, particularly in terms of economic growth, military involvement, and global impact. During WWI, the United States was a late entrant, and its contribution, while pivotal, did not lead to a dominating post-war position. The number of American troops and the economic impact were significant but not transformative on a global scale. In contrast, WWII marked a watershed moment in U.S. history. The United States emerged as an economic and military superpower with full employment, advanced technologies, a strong military, and it was the only nation with the atomic bomb at the end of the war. The American dollar became the world's standard currency, and U.S. companies expanded globally.
During WWI, the U.S. saw a smaller volunteer army and had to navigate internal dissent and a complex international stance, especially considering President Woodrow Wilson's initial foreign policy disinterest. By WWII, over 16 million Americans served in the armed forces, significantly influencing both the home front and the battlefield. The U.S. had a gigantic industrial capacity and was able to provide millions of fresh troops, which were critical in achieving victory.
In comparison, WWI did not end European conflict and led to the conditions that spurred WWII. The difference in the American contribution between the wars is marked by the transition from a late, albeit important, participant in WWI to a leading, economically thriving, and militarily dominant superpower in WWII. This transition also reflected in the global influence and stance of the U.S. post-WWII, setting the stage for the Cold War era.
