John Green explains how World War II prevented the rise of new empires by weakening major imperial powers and leading to the emergence of the United States as a superpower.
John Green cites World War II as a reason why no new empires have risen since its end because the war led to the decline of major imperial powers, leaving them unable to maintain their colonial possessions due to the human and economic devastation caused by the conflict.
This scenario shifted the global power dynamics, allowing the United States to emerge as the world's greatest superpower after World War II, with considerable economic and military strength.
The aftermath of World War II reshaped international relations and paved the way for the establishment of new structures like the United Nations to prevent future large-scale conflicts.
