Bombing Japan was the best way to end WWII

I'll counter each and every one of your points, And then attack back with my own. Dropping the nukes weren't overkill considered it was the most necessary action to take in war. You aren't thinking about the enemies feelings but rather how you can win. There were no other viable options (which I'll discuss later). Most of the deaths were civilians, But we also dropped pamphlets down into Japan, Warning them of our weapons-of-mass-destruction, And how they will be used in military areas, Which both Hiroshima (Military factories and other facilities) and Nagasaki (Military ports and shipbuilding factories) were. Robert Oppenheimer, The guy who made the atomic bomb, Said that he was expecting only a fraction of the civilian deaths that there were, Due to the air raid sirens that would have gone off, Giving the Japanese plenty of time to get to their shelters and survive the blast. One bomb wouldn't have been enough. The Americans wanted to show Japan it wasn't some "freak of nature" that would only occur once, Combined with the quick one-two effect dropping both bombs on Japan would have, Crippling not only the economy of Japan but also the morale. After all, Even if the government surrendered, If they couldn't show the people why it was better for them to surrender, The people would've overthrown the government, Seized control, And continued the war. The League of Nations laws is the biggest factor contributing to the "illegal" or in this case "war crime" aspect of dropping the bombs. To that I bring up, Not only was America not in the League of Nations (so the law wouldn't apply to them), They contact Britain, And Britain (who was in the LoN) agreed dropping the bombs was the best course of action. The only other bombs we had were the B-29s, Which would've cost: more lives (the pilots shot down, Along with more bombing targets), More time (which would've increase casualties and more requests for resources), And more money (one atomic bomb cost 4000 B-29s). The atomic bombs were both dropped with accuracy, As the military chose the best of the best pilots to drop the bombs. Accuracy was not an issue. My original argument was engineered to be weak, So I could counter your counterpoints. Now, Onto some of my attacking points. A-Bombs were the way to go, The only viable option. What about a demonstration? Not only would this have been a waste of the sole purpose of this bomb (destruction), There was also no guarantee it would work, Along with no guarantee that the Japanese would believe it to be real, As nothing like this had ever been seen in public before. What about a ground invasion? 1. 7 to 4 million American casualties, With an estimated 10 million Japanese casualties. Seems a bit more than just the 175, 000 in both the bombings. What about waiting for surrender? The government had talked about surrender, But the Japanese people were so devoted to not only their Emperor but also fighting the Americans, They would have continued on fighting us, Whether organized militarily by the government, Or taking into their own hands and fighting guerilla style, Which would've taken around 10 years to get under control. It's now your floor, But you may not like how I remodeled it for you.
