During the twentieth century, the United States transitioned from a predominantly isolationist stance to a leading global superpower. This shift was marked by active involvement in World War I and World War II, where the US played crucial roles in shaping post-war orders. The Cold War further solidified its influence, as it engaged in ideological, political, and military confrontations with the Soviet Union. By the century's end, the US emerged as a dominant force in international politics, economics, and culture.
