The decision to drop the atomic bombs on Hiroshima and Nagasaki did work to have the Japanese surrender without appeasment.

A strange way to describe it - 'introduced'. 'I would like you to meet a nuclear weapon......' The bombs were dropped on civilian cities Hiroshima and Nagasaki, without any warning, in August 1945.
it ended the war. Japan surrendered without conditions.
Why was Pearl Harbor attacked without warning also? You will find online that we dropped leaflets over the cities before we destroyed them. I'm not sure if we actually did drop leaflets, but if we did, we did not drop them on Nagasaki or Hiroshima. They were dropped on other cities after the destruction of the others.
The Japanes attacked Pear Harbor without notice.
It was hard to Japan tu surrender after the bombs. No will be my answer.
Actually, it has been decades without radiation that came from the atomic bombs.

At the end of World War II, few questioned Truman's decision to drop the atomic bombs on Hiroshima and Nagasaki. Most Americans accepted the obvious reasoning: the atomic bombings brought the war to a more timely end. They did not have a problem with over one hundred thousand of the enemy being killed. After all, the Japanese attacked America, and not the other way around. In later years, however, many have begun to question the conventional wisdom of "Truman was saving lives," putting forth theories of their own. However, when one examines the issue with great attention to the results of the atomic bombings and compares these results with possible alternatives to using said bombs, the line between truth and fiction begins to clear. Truman's decision to use the atomic bomb on Japan was for the purpose of saving lives and ending the war quickly in order to prevent a disastrous land invasion.
