Question

during the us occupation of japan after world war ii, japans military was
used to help rebuild cities,
replaced by the us military,
used to help build a police force,
dismantled by the us military.

Explanation:

After World War II, the U.S. occupation of Japan aimed to demilitarize the country. This involved dismantling Japan's military. Rebuilding cities was more about civilian - led or U.S. - funded civilian projects. The U.S. did not train Japan's military as part of the demilitarization process. Building a police force was a separate aspect of post - war governance reform, not related to using the existing military.

Answer:

dismantled by the US military.
