America, by the time of WWII, had become an industrial superpower, though it had yet to, as Teddy Roosevelt would say, "flex it's muscles". The time to do so, and subsequently establish itself as the world's only superpower, was WWII. America rose to the occasion, and only through their industrial might were they able to support the massive amount of resources necessary to fund the war effort needed to fight the war in Africa, Europe, and Asia. Another thing, outside of resources, that any military force needs to morale. For America, this often came in the form of Coca-Cola, which was shipped out to the troops en mass, with some Coca-Cola manufacturing plants being established on the way. The Germans and Japanese both rejected Coca-Cola, saying it represented how little America was capable of, that it was represented by a soda brand. However, America won the war, and so did Coca-Cola, which was now expanded to new heights in the various countries liberated during the war.
