The History of the Twentieth Century

For India, like Australia, the entry of Japan into the war meant it was no longer a distant, European struggle. By May 1942, the Imperial Japanese Army was at the Indian border.

In 1942, many Americans feared a Japanese invasion of the West Coast of the US or Canada was imminent. Regrettably, these fears led to the belief--unsupported by facts--that the ethnic Japanese population on the West Coast represented a dangerous fifth column of potential spies and saboteurs.

Sometime in the autumn of 1941, a decision was made among the Nazi elite to murder every Jewish person in Europe--or within reach, anyway. No record exists of how that decision was made, but we have a very detailed record of how it was carried out.

The winter of 1941-42 was not a happy one for the German Army. On the Eastern Front it was battered by a record cold winter and a Soviet counteroffensive. In North Africa, a British offensive pushed Erwin Rommel and his Afrika Korps all the way back to central Libya, from where he had begun.

After the sinking of Bismarck, the Germans abandoned surface raiding in the Atlantic and turned to their greatest naval strength: submarine warfare.

The Luftwaffe's bombing campaign over England did not force a British capitulation. Can RAF Bomber Command force a German capitulation?

The Japanese Army's greatest victory; the British Army's greatest defeat.

The attack on Pearl Harbor ended the political division in the US between interventionists and isolationists. Now the US was united as never before.

The Japanese attack the US naval base at Pearl Harbor.

The Japanese give up on peace talks with America and began prepare for war.

The defining features of the nation of Panama are its abundant wildlife and that it is the place where the world's two largest oceans are at their closest.

The upper levels of Japanese government (and, more important, the military) increasingly came to the view that war with the United States was necessary if Japan was to survive.

At the end of the rasputitsa, the mud season, the German Army had one final, narrow opportunity, to win the war against the USSR before winter.

Even before the first German soldier crossed the frontier into the USSR, the Nazi government in Berlin had a plan for administering occupied Russia.

The German invasion of the USSR went brilliantly for the first 2-3 weeks, but instead of collapsing as expected, the Red Army only got stronger.

On June 22, 1941, Germany began an invasion of its erstwhile trade partner, the USSR. 

The Dust Bowl ravages the central United States, Charles Lindbergh's infant son is kidnapped, the America First movement opposes US involvement in the war.

Germany executes its invasions of Yugoslavia and Greece, and the Axis encourages an anti-British coup in Iraq.

As Germany made preparations to assist its ally Italy in the war against Greece, a coup in Yugoslavia prompted Adolf Hitler to order the invasion of that country as well. 

In summer of 1940, even as the Battle of Britain was just getting started, Adolf Hitler was already laying plans for war with the Soviet Union.

After the fall of Poland, British Intelligence's codebreaking operation at Bletchley Park became the center of efforts to decrypt messages from the Germans' supposedly unbreakable Enigma machine.

The British had been hugely successful at breaking German codes in the First World War. The Germans were determined not to let that happen again. This time they had Enigma, a code machine that produced messages that could not be decrypted. Or so the Germans believed.

The navy Germany had at the outbreak of the Second World War was only a small fraction of what the Allies had arrayed against it. But the Fall of France and the entry of Italy into the war changed things dramatically and created opportunities at sea that Germany had never had in the last war.

In 1940, the British government was in the frustrating position of funding research on a number of promising projects that would be valuable to the war effort, but with the Battle of Britain in full swing, British factories had to turn out fighter planes as fast as they could. There was no room for development of experimental new technologies, so the British turned to the United States

Italy's invasion of Greece was disastrous. With the British also advancing in North Africa, and a surprise air attack disabling three Italian battleships, it was no longer possible to pretend that Italy was a equal of Germany.
