The Japanese Government didn't want an unconditional surrender as it would have meant the Emperor (Who was seen as quasi-divine) would have potentially been tried for war crimes and executed. They didn't care about their citizens, just the Emperor. Fantastic video which explains everything: [this video]

> Whereas Japan would’ve continued the war and brought it back to the US mainland eventually. This is simply ahistoric. Japan was on the brink of loss and everyone knew it (including all of Japan's military and political leaders) -- Japan was already suing for peace long before the bombs were dropped. The main sticking point was the conditions of surrender and the Japanese were deluded (partially by the US, intentionally or not) into thinking Russia could get them more favourable surrender conditions.

> the US only used atomic weapons to end a devastating war inflicted upon it by a ferocious and fanatical adversary This isn't true at all. You don't need to bomb civilian cities to end a war. The Japanese government, specifically the emperor had already indicated they wanted to negotiate. They were already well aware they couldn't win the war. There is far, far more evidence that the U.S. just couldn't help itself and wanted to demonstrate our/their new weapon: "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." - Chester W. Nimitz, Commander in Chief of the U.S. Pacific Fleet In true U.S
