we defeated the Japanese thanks to our weapons from our factory workers
As they were working in the factories, they heard planes flying by and they thought the military was doing another drill until they heard a bomb go off night next to the factory.
They all ran into the streets to see what was going on and they were all scared, until the military rushed them all underground.
They heard a few more bombs and then it all of a sudden stopped. Their military was much more powerful then they thought and took down all the Japanese plans. They saved millions of lives and none of the American lives were taken.
