Setting the Stage: A World at War

Setting the Stage: A World at War

The autumn of 1938 brought an unsettling quiet to Europe. In the German Reich, Adolf Hitler had just returned triumphant from the Munich Conference, having extracted the Sudetenland from Czechoslovakia without a single shot fired. The Western powers, desperate to avoid war, had capitulated to his demands, and the British Prime Minister Neville Chamberlain flew home claiming he had achieved "peace in our time." In Tokyo, military planners were finalizing strategies for expansion in Asia, confident that the distracted European powers would offer little resistance. In Rome, Benito Mussolini surveyed his African ambitions with growing confidence. The world, it seemed, had decided that appeasement could contain the forces of fascism.

But beneath the surface of diplomatic maneuvering and political theater, something far more dangerous was taking shape. In laboratories scattered across three continents, in secret facilities hidden beneath mountains and buried in deserts, a different kind of competition had already begun. This was not a race measured in territory or armies, but in atoms split and particles accelerated, in radio waves bounced off distant aircraft and flames roaring through turbine blades spinning faster than sound itself. The war that was coming—and everyone in the know understood it was coming—would be decided not merely by the size of armies or the tonnage of navies, but by who could first unlock the secrets of nature itself and bend them to purposes of destruction.

By the late 1930s, the world had witnessed the catastrophic transformation that industrial technology could bring to warfare. The First World War had demonstrated this with horrifying clarity: machine guns mowing down rows of soldiers advancing in formations their grandfathers would have recognized, artillery shells falling in patterns that turned the soil of Belgium and France into a lunar landscape of shell craters and barbed wire, chemical weapons choking soldiers in their trenches, and aircraft dropping bombs on cities for the first time in history. The Great War had killed approximately seventeen million people and wounded another twenty million, leaving an entire generation traumatized and a map of Europe redrawn in blood and treaty clauses that would prove to be temporary at best.

Yet the weapons of 1918, terrifying as they were, represented only the opening chapter of a technological revolution that had barely begun. The principles underlying those weapons—the internal combustion engine, the high-explosive shell, the propellant chemistry of cordite and guncotton—had been largely worked out in the nineteenth century. The scientists and engineers of World War I had largely applied existing knowledge to the problems of warfare, refining and scaling rather than fundamentally transforming.

What was coming in the next war would be different in kind, not merely degree. The 1930s had witnessed a cascade of breakthroughs in physics, chemistry, and engineering that were only beginning to be understood, let alone harnessed. The discovery of the neutron in 1932 had opened the door to understanding atomic structure in ways that would soon make the concept of atomic energy—not merely atomic weapons—thinkable. The development of quantum mechanics was revealing the strange rules governing subatomic particles, rules that would enable technologies previously confined to science fiction. Radio astronomy was born in 1937 when Karl Jansky detected radio waves from the center of the Milky Way. Television, first demonstrated publicly in 1927, was rapidly becoming practical. The mathematics of feedback loops and servomechanisms, theoretical work that would underpin automatic control systems, was being developed by mathematicians and engineers who could scarcely imagine the applications to come.

These were not merely interesting curiosities. They were weapons waiting to be forged, and every major power understood, with varying degrees of clarity, that whoever mastered them first would possess an overwhelming advantage. The coming war would not be simply a contest of industrial production and military organization, though those would remain crucial. It would be, fundamentally, a contest of scientific discovery and technological application—a race to transform the laboratory into the battlefield before one's enemy could do the same.

The Gathering Storm: Geopolitics in the Late 1930s

To understand why this technological race would become so urgent, and why it would produce such dramatic results, one must first appreciate the geopolitical landscape that made war not merely possible but probable. The Treaty of Versailles, signed in 1919, had imposed such punishing terms on Germany that it had created, in the words of the economist John Maynard Keynes, who was present at the negotiations, "a Carthaginian peace" that virtually guaranteed future conflict. Germany lost territory, faced severe restrictions on its military, and was saddled with reparations that the Allied powers themselves recognized as economically impossible to pay. The treaty thus accomplished something remarkable: it united the German people across class and ideological lines in a shared sense of victimhood and humiliation that would prove far more politically useful to ambitious demagogues than any economic grievance.

Adolf Hitler and the National Socialist German Workers' Party came to power in 1933, riding on waves of resentment, economic desperation, and the fractured nature of German parliamentary democracy. Once in power, Hitler moved with systematic ruthlessness to overturn the Versailles restrictions, remilitarize Germany, and pursue territorial expansion that he framed in the language of providing "living space" (Lebensraum) for the German race. The remilitarization of the Rhineland in 1936, the annexation of Austria in the Anschluss of 1938, and the dismemberment of Czechoslovakia through the Munich Agreement and subsequent occupation of what remained of the Czech lands in March 1939 demonstrated both the weakness of the Western democracies' will to resist and the rapid restoration of German military power under the Nazi regime.

But Germany's ambitions extended far beyond European conquest. Hitler's worldview was apocalyptic in its racial dimensions: the struggle for existence among races, with the so-called "Aryan" race destined either to rule or to be exterminated by the forces of international Jewry and "Bolshevism," which Hitler regarded as fundamentally identical threats. This ideological framework, however delusional, had concrete policy implications. The invasion of the Soviet Union, which Hitler ordered in 1940 and which commenced in June 1941, was not merely a war of conquest but a war of annihilation, intended to destroy Bolshevism as a political force and to acquire the agricultural and resource wealth of European Russia for German colonization. That this campaign would prove to be the greatest military disaster in German history, consuming the cream of the German army and ultimately leading to the destruction of the Third Reich, was by no means obvious in 1939. Hitler had achieved everything he had attempted, and his generals, for all their professional expertise, had been consistently outmaneuvered by political audacity and the willingness to take risks that more cautious commanders would have rejected.

Japan, meanwhile, had been pursuing its own imperial ambitions throughout the 1930s. Following the Mukden Incident of 1931, in which the Japanese military staged a railway sabotage to justify the invasion of Manchuria, Japan had established a puppet state in northeastern China and began extracting its resources to fuel Japanese industrial development. The Marco Polo Bridge Incident of July 1937 marked the beginning of full-scale war between Japan and China, a conflict that would drag on until 1945 and see atrocities that shocked the world—the Nanjing Massacre of
