What country played the main part in winning World War 2?
This is a difficult question due to the fact the the major three
each played a crucial role in defeating Nazi Germany. Without
Britain, the Germans would have conquered all of Europe and then
been able to focus on the Soviet Union. Also without England, there
would have been no place to stage Operation Overlord. This means
that they would have had to invade Europe thru southern France. The
Germans would have made this the key point of resistance.
Without the Soviet Union, the Wehrmacht would have never been
bled to death. Remember Churchill could not believe it when the
planners told him they were concerned that the invasion of Sicily
might fail because there was the possibility of 2 German Panzer
divisions. The Soviets dealt with well over 150 divisions on the
eastern front. Also the losses suffered by the Soviet Union would
have forced either the UK or the US to the negotiating table. The
Soviets lost, some say, over 20 million direct and indirect
And then there is the US. Without lend lease, neither the UK nor
the Soviet Union could have continued the struggle. Also the US'
daylight bomber campaign destroyed the Germans ability to make the
implements of war. Without these two ingredients the Germans would
have won. So to answer your question it is really impossible to say
that this or that country was the key to the defeat of Nazi
Germany. Without the UK, there would have been no US lend lease.
Without the Soviet Union, the Germans would have been able to
concentrate solely on the UK and destroyed them. Imagaine no
Operation Barbarossa. This would have meant that Hitler could have
sent as many Panzer divisions to Rommel as he needed. Also he would
have had ample Luftwaffe assets to drive the Royal Air Force from
the skies. In this scenario, Rommel would have succeeded in
defeating the British 8th Army, seizing Egypt and the Suez and
ultimately all the oil in the middle east. And never forget the
southern route for lend lease, with the Germans in control, this
would have been closed. And this might have also forced Turkey into
the war, although it is arguable whether this would have been a
help or hinderance upon Germany, as Turkey was not ready to fight a
major war. And we all know that without the US the other two could
not have managed to keep on fighting the Germans.
