I want to know the answer to the following question:
When did Artcle 3 of the Treaty of San Francisco come into effect?
All the background I'm provided with is that "In Article 3 of the Treaty of San Francisco between the Allied Powers and Japan, which came into force in April 1952, the U.S. put the outlying islands of the Ryukyus, including the island of Okinawa—home to over 1 million Okinawans related to the Japanese—and the Bonin Islands, the Volcano Islands, and Iwo Jima into U.S. trusteeship.". Is that enough to answer the question?
Answer: yes
