How did the Battle of Midway change or impact the US and its policies?

During World War II, the Battle of Midway (in June 1942) impacted the United States and its policies in a dramatic way: it provided a decisive 'check' upon the offensive actions of Imperial Japan while also dealing the Japanese Navy a defeat from which it never recovered. For these reasons, this battle may be said to have had a direct effect upon the continued survival of the United States as a whole.
