American war production turned the tide in favor of the allies.

America entered WWII unwillingly and largely unprepared. However, the American people quickly rallied and transformed the American economy into the best and most efficient and productive military hard-ware making machine in the world.

President Roosevelt expanded the army to 227, 000 soldiers within days of Germany's invasion of Poland. The British Prime minister at the time alluded to the American economy as a gigantic boiler under which once the fire was lighted, there was no limit to the power it could generate.

American production turned the tide of the war in favor of the allies and the USA played a crucial role in the defeat and surrender of the Axis powers.
