On Sept. 2, 80 years will have passed since representatives of Japan and the Allied powers signed an agreement formalizing the end of World War II aboard the USS Missouri. That document formalized Japan’s surrender and initiated a postwar occupation that would last for seven years.

The goal of the Occupation: reform Japan into a country that would never again wage a war of aggression, and one that would espouse the values enshrined in the recently signed U.N. charter.
