Assuming the Second World War begins and ends without any sort of intervention by the United States (the threat of Germany and Japan either peters out or is crushed by the other powers), then what would be the changes to American industry, economics, policy, and military, in the aftermath of the 'triumph' of isolationism? Generally speaking, what is the USA like in the following decades? Is what Eisenhower termed the 'military-industrial complex' avoided? Does America grow into foreign affairs outside the American continent, or does it keep its limits in the New World? Does it generally shift to the left or to the right?
