Well, since you seem to be unaware of the reasons Truman OK'd the bombs...you seem to think that there was another way to defeat the Japanese, that wouldn't involve the deaths of hundreds of thousands of US servicemen.
By all means, share the alternatives...
From January 1945 on there were many conversations both within the Japanexe War Cabinet..... The Big Six regarding surrender, and attempts to communicate conditions with the Allies who were firm that any surrender be unconditional. The Potsdam Declaration became the last word from the allies which gave conditions of surrender and warnings that non acceptance would ensure an attack which would bring about the destruction of Japan. July 27, 1945, the Japanese government stood firm and announced a policy of silence in reply. On July 30th and August 2, evidence shows that despite their silence in talking with the Allies about conditions of surrender, they were still talking among themselves trying to reconcile their differences with some stubbornly refusing terms of 'uncondition' and others concerned about their weakening strength and the threat of Russia entering the war against them as she had withdrawn from a previous treaty in April of that year.
Hiroshima was hit with the first Atomic Bomb on August 6, 1945, and on August 9, 1945, while in meeting, the Big Six received word of Russia's invasion of Manchuria, and the devestation of Nagasaki by another Atomic bomb.
Related to the OP of this thread is the incidence of information under torture noted in historical account as follows:
The full cabinet met on 14:30 on August 9, and spent most of the day debating surrender. Like the Big Six had already done, the cabinet split, with neither Tōgō's position nor Anami's attracting a majority.[76] Anami told the other cabinet ministers that, under torture, a captured American B-29 pilot had told his interrogators that the Americans possessed 100 atom bombs and that Tokyo and Kyoto would be bombed "in the next few days". The pilot, Marcus McDilda, was lying. He knew nothing of the Manhattan Project, and simply told his interrogators what he thought they wanted to hear in order to end the torture. The lie, which caused him to be classified as a high-priority prisoner, probably saved him from beheading.[77] In reality, the United States would have had the third bomb ready for use around August 19, and a fourth in September 1945.[78] The third bomb would probably have been used against Tokyo.[79]

While the information given by the soldier under torture and threat for his life was erroneous....... it is most interesting how well just a little bit of smarts on his part, totally ignorant of the Manhattan project, and educated guesses of consequences worked to both save his life in captivity, and increase the impact of the first two bombs upon the building horror of imminent destruction if the Big Six continued to ignore surrendering. There continued a hesitancy on their part to accept surrender, but:
At 12:00 noon Japan standard time on August 15, the Emperor's recorded speech to the nation, the Gyokuon-hōsō (Imperial Rescript on surrender), was broadcast:
In spite of the bitter tragedy of war and brutality suffered on both sides, its worthy to note that although unconditional surrender was required..... the terms of our acceptance afterward and humane treatment:
Japanese officials left for Manila on August 19 to meet Supreme Commander of the Allied Powers Douglas MacArthur, and to be briefed on his plans for the occupation. On August 28, 150 U.S. personnel flew to Atsugi, Kanagawa Prefecture, and the occupation of Japan began. They were followed by USS Missouri, whose accompanying vessels landed the 4th Marine Division on the southern coast of Kanagawa. Other Allied personnel followed.
MacArthur arrived in Tokyo on August 30, and immediately decreed several laws: No Allied personnel were to assault Japanese people. No Allied personnel were to eat the scarce Japanese food. Flying the Hinomaru or "Rising Sun" flag was initially severely restricted (although individuals and prefectural offices could apply for permission to fly it). The restriction would be partially lifted in 1948 and completely lifted the following year.
That is testimony to our treatment of a valiant and courageous, though misguided people.
We live in a fallen world. A world in which there will always be wars and rumours of wars. The treatment of soldiers in war, in combat and as prisoners is considerably different than the treatment of people caught in the act of terrorism and crimes: Still justice requires that the charges are brought forth with the evidence to convict them. Information received because of interrogation techniques, not available otherwise, which is self incriminating, if allowed at all concerning conviction, should carry the most lenient of consequences and be available for challenge on appeal. Our freedoms are best preserved both by exercising and by expecting and enforcing this recognition by others. Those who will stubbornly refuse to comply, not only snub the laws of God, but also the natural laws which holds civilizations and societies together in respect for life and justice. It may be that for those who's only language is brutality, cannot have any understanding except on their own terms.
I would not wish to be in charge of any decisions for the sake of my own conscience..... nor do I wish to be overly critical of others who have position and rank to make these difficult decisions and must live with their own conscience afterward. It is futile to charge them against Christian standards when for the most part many most likely aren't Christian: Therefore they are judged by the natural law..... or the laws implimented by governments and nations which have their foundations in natural law.
Our people and our nation has been so blest by God: I would to God that we would repent of our errors in deceiving and allowing ourselves to be deceived, in all the killings of innocents..... but most particularly the intentional killing of the unborn..... of the greed for money or our trust that it makes us secure...... or our willing deception to follow men instead of God and to trust men to solve the problems within society (economic, social, political) instead of first seeking the cousel and wisdom of God........ and in that repentance, turn back to God with committments which look to him for guidance in everything we do. I wish for the people of the world, that they could know Jesus!
