What if America remained independent?
What if the world and the war in the MITHC goes almost similar to the show’s timeline. America gets bombed to hell, starvation, depression, Axis defeat Russia, Britain, France, Australia, etc but somehow the USA manages to pull off the atomic bomb forcing Germany and Japan to give up on their plans for the occupation of the US. So, the U.S., Canada, Mexico, etc maintain their independence with no land lost with the exception of America losing Hawaii.
So, Germany and Japan still rule most of the world. The US is the ruling influence in the western hemisphere but the country itself is in utter shambles after being overwhelmed by the depression and Axis bombing campaigns. American cities lie in ruins.
What does this world look like by 1962? What does the USA look like? Can it recover?
