What were the after affects of World War I?

Influenza spread by insanitary military conditions and troop movements killed millions, mostly in Asia but also in Europe, the Americas and Africa. Europe declined in economic and military power, encouraging independence movements to seek independence in its overseas colonies. Russia went Communist. The United States emerged greatly strengthened. Industrial growth picked up in Japan and India following the wartime disruption of British exports. Anger at the postwar settlement in central Europe led to the rise of anti-Treaty settlement, culminating in the rise of fascism and nazism. Heavy wartime military losses contributed to British and French reluctance to confront German and Italian expansionism in the late 1930s.
