“How did Operation Barbarossa and the Japanese attack on Pearl Harbour affect the outcomes of WW2?”

Operation Barbarossa and Japan’s attack on Pearl Harbour directly led to the defeat of Hitler’s Germany and its allies during World War Two. These two events were major causes in the outcomes of the war. Operation Barbarossa was Hitler’s offensive invasion plan into the USSR. However, the plan was floored, as Hitler had out stretched his resources and underestimated the enemy. It also led to Germany and its allies facing war on two fronts, which was the downfall of the German empire in the First World War. Operation Barbarossa took the focus of war away from Britain in the West, and aimed it on Russia in the East. This proved fatal, as Britain was not fully crushed and was able to regroup with American help to mount a counter-offensive on Germany’s Western flanks at Normandy later in the war. Japan’s pre-emptive attack on America’s major air and naval base in the Pacific, Pearl Harbour, drew America into the war. This proved decisive, as America knocked Japan out of the war through the use of Atomic weapons and joined forces with the Allies to Destroy Hitler’s Germany in Europe.

On June 22nd 1941, Hitler launched Operation Barbarossa, the biggest land invasion the world had ever seen (Calvocoressi, 1972, p116).

Hitler did not want to make the grave mistake of dragging the conflict out into the harsh Russian winter. Operation Barbarossa had also opened Germany up to war on two fronts, and victory in the East needed to be swift so he could direct his armies West ward to finish off the British before they had time to regroup.

Hitler’s strategy proved to be over-ambitious, as it was based on inadequate resources and an underestimation of the enemy (Seaton, 1971, p338). Russia had come a long way in military terms since the disasters of the First World War. Their logistic ability to organize troops had far exceeded Hitler’s thinking, and with winter fast approaching German forces needed swift victories. These were not to come as Russian forces retreated into the heart of Russia. Winter came three weeks premature and the weather was Hitler’s greatest enemy (Fuller, 1948, p124). Soon, the once easy advance across Russia became a long, ...
