Annotation
Wells gave Europe forty to fifty years before it could reassemble the energy for another world war. It took fifteen. The bitter irony is that Wells correctly identified every ingredient — he attacked Italian Fascism and warned about Hitler after the Beer Hall Putsch in the same book — but dramatically underestimated the speed at which exhaustion could curdle into something worse. Europe was not too bankrupt for war; it was incubating one.
What Actually Happened
Europe reassembled the energy for another world war not in forty or fifty years but in fifteen. Germany rearmed openly from 1935; the Second World War began in 1939, just twenty-one years after the Armistice. The conflict exceeded the Great War in every dimension — more combatants, more casualties, more territorial devastation — culminating in the industrialized genocide of the Holocaust and the use of atomic weapons.
