Did Truman regret dropping the bomb?

Answer 1

Actually FDR made the decision to drop the atomic bomb prior to his death, Truman did not even know of the atomic bomb at the time this decision was made. When he was informed of the atomic bomb after FDR's death he only decided to continue all of FDR's decisions and policies without change. The Army Air Forces implemented FDR's decision in an order to drop the bombs "as soon as they became available".

Truman's only actual decision on the use of the atomic bomb was to stop dropping them after the Japanese indicated their willingness to surrender on August 14.

Truman continued his policy against the further use of atomic bombs by firing General MacArthur as soon as he proposed their use during the Korean War and replacing him with General Ridgway.

Answer 2

Truman has no regret of doing anything. If he regret it, he would not have dropped a second one after dropping the first one.

He was planning to drop a 3rd and 4th bomb as well.

Truman did not "regret" dropping the bomb as it ended the war and brought the results intended of the Japanese Imperial Army. However throughout his life, the devastation stayed on his mind and he did look with a grain of salt upon the morality and the results of the bomb. You cannot say he regretted it but he did feel badly and such about the devestation and stayed very skeptical about the whole thing throughout his life. For lack of a better word, regret could be used but it is not totally regret since he felt he was saving American lives, but he did feel woeful about the devastation such a weapon caused. It is very hard to explain and maybe I should read more about it but hopefully you get the point.

Answer 3

The toughest decision of his presidency as cited by him was his decision to enter the Korean War.
