Here's the opinions of Generals Eisenhower & MacArthur & Admirals Nimitz & Leahy & others about Japan's surrender prior to bombimg.

"Those who argue that the bombings were unnecessary on military grounds hold that Japan was already essentially defeated and ready to surrender.
One of the most notable individuals with this opinion was then-General Dwight D. Eisenhower. He wrote in his memoir The White House Years:
"In 1945 Secretary of War Stimson, visiting my headquarters in Germany, informed me that our government was preparing to drop an atomic bomb on Japan. I was one of those who felt that there were a number of cogent reasons to question the wisdom of such an act. During his recitation of the relevant facts, I had been conscious of a feeling of depression and so I voiced to him my grave misgivings, first on the basis of my belief that Japan was already defeated and that dropping the bomb was completely unnecessary, and secondly because I thought that our country should avoid shocking world opinion by the use of a weapon whose employment was, I thought, no longer mandatory as a measure to save American lives."[67][68]
Other U.S. military officers who disagreed with the necessity of the bombings include General Douglas MacArthur (the highest-ranking officer in the Pacific Theater), Fleet Admiral William D. Leahy (the Chief of Staff to the President), General Carl Spaatz (commander of the U.S. Strategic Air Forces in the Pacific), and Brigadier General Carter Clarke (the military intelligence officer who prepared intercepted Japanese cables for U.S. officials),[68] and Admiral Ernest King, U.S. Chief of Naval Operations, Undersecretary of the Navy Ralph A. Bard,[69] and Fleet Admiral Chester W. Nimitz, Commander in Chief of the Pacific Fleet.[70]
"The Japanese had, in fact, already sued for peace. The atomic bomb played no decisive part, from a purely military point of view, in the defeat of Japan." Fleet Admiral Chester W. Nimitz, Commander in Chief of the U.S. Pacific Fleet.[71]
"The use of [the atomic bombs] at Hiroshima and Nagasaki was of no material assistance in our war against Japan. The Japanese were already defeated and ready to surrender." Admiral William D. Leahy, Chief of Staff to President Truman.[71]
The United States Strategic Bombing Survey, after interviewing hundreds of Japanese civilian and military leaders after Japan surrendered, reported:
"Based on a detailed investigation of all the facts, and supported by the testimony of the surviving Japanese leaders involved, it is the Survey's opinion that certainly prior to 31 December 1945, and in all probability prior to 1 November 1945, Japan would have surrendered even if the atomic bombs had not been dropped, even if Russia had not entered the war, and even if no invasion had been planned or contemplated."[72][71]


What was originally the Hiroshima Prefectural Industrial Promotion Hall has now been turned into the Hiroshima Peace Memorial. The atomic bomb exploded almost directly overhead.
The survey assumed that continued conventional bombing attacks on Japan—with additional direct and indirect casualties—would be needed to force surrender by the November or December dates mentioned.
Many, including General MacArthur, have contended that Japan would have surrendered before the bombings if the U.S. had notified Japan that it would accept a surrender that allowed Emperor Hirohito to keep his position as titular leader of Japan, a condition the U.S. did in fact allow after Japan surrendered. U.S. leadership knew this, through intercepts of encoded Japanese messages, but refused to clarify Washington's willingness to accept this condition. Before the bombings, the position of the Japanese leadership with regards to surrender was divided. Several diplomats favored surrender, while the leaders of the Japanese military voiced a commitment to fighting a "decisive battle" on Kyûshû, hoping that they could negotiate better terms for an armistice afterward. The Japanese government did not decide what terms, beyond preservation of an imperial system, they would have accepted to end the war; as late as August 9, the Supreme War Council was still split, with the hard-liners insisting Japan should demobilize its own forces, no war crimes trials would be conducted, and no occupation of Japan would be allowed. Only the direct intervention of the emperor ended the dispute, and even then a military coup was attempted to prevent the surrender.
Historian Tsuyoshi Hasegawa's research has led him to conclude that the atomic bombings themselves were not even the principal reason for capitulation. Instead, he contends, it was the swift and devastating Soviet victories in Manchuria that forced the Japanese surrender on August 15, 1945."

It was the 1st nuclear attack anywhere & it was uncalled for! It was a war crime & a crime against humanity.
