WW2 didn’t officially end until 1952 with the Treaty of San Francisco.
http://en.wikipedia.org/wiki/Treaty_of_San_Francisco
Treaty of San Francisco (or commonly known as the Treaty of Peace with Japan, Peace Treaty of San Francisco, or San Francisco Peace Treaty), mostly between Japan and the Allied Powers, was officially signed by 48 nations on September 8, 1951, at the War Memorial Opera House in San Francisco, California, United States. It came into force on April 28, 1952.
This treaty served to officially end World War II, to formally end Japan’s position as an imperial power, to allocate compensation to Allied civilians and former prisoners of war who had suffered Japanese war crimes, and to end the Allies’ military occupation and return sovereignty to Japan. This treaty made extensive use of the UN Charter[1] and the Universal Declaration of Human Rights[2] to enunciate the Allies’ goals.
Hostilities ceased in September as another poster pointed out, not as I stated, in August. This sounds like the occupation and final “you’re on your own” government left by MacArthur was what happened in the “final” treaty.
There will be no treaty with Islam, ever.
