What impact did ww2 have in the relative roles of the us and britain in the world

The World War II had huge impact on the roles of multiple countries on the global political scene. Some managed to go to the top, others slipped slightly, some slipped dramatically in their global role.

The United States were the biggest winners in that department. They became the super power of the world. Their reputation grew significantly, and their political and military influence around the globe skyrocketed.

Britain, on the other hand, had a slight slip. After the war it was not a country that was a global super power. Exhausted economically and in ruins, Britain had to focus on reparations of the country, which also meant losing its numerous colonies. That led to a decline of the British influence on the global political scene.
