Question

the potsdam declaration included
o guidelines for the use of nuclear weapons
o terms for the surrender of axis forces with a threat of force if they failed to do so
o terms for japanese surrender with a threat of force if they failed to do so
o a promise to not use atomic weapons

Explanation:

The Potsdam Declaration was issued in 1945. It was mainly about the terms for Japan's surrender. It stated that if Japan did not surrender, it would face "prompt and utter destruction". It did not include guidelines for nuclear weapons use (nuclear weapons were used after the declaration), nor was it about Axis forces in general (as most Axis powers had already surrendered), and there was no promise to not use atomic weapons (atomic bombs were dropped on Japan after the declaration).

Answer:

terms for Japanese surrender with a threat of force if they failed to do so
