Not much longer after the ANZUS Treaty was the San Francisco Treaty. It was created by the US and signed by the Japanese on September 8, 1951.
The Treaty was created to make peace between these two countries that have been fighting for quite sometime now. It started with the Japanese attacking the US at Pearl Harbor, Hawaii on December 7, 1941. The US was VERY angry about this. So angry in fact that they wanted revenge. The US came back with full force and attacked Hiroshima August 6, 1945. Apparently that wasn’t even enough, three days later on August 9, 1945 we bombed Nagasaki because they wouldn’t surrender the war.
Japan then surrendered on September 2, 1945. Six years later the US was done playing games and didn’t want japan to try any attacks again. therefore they created the San Francisco Treaty.
