He doesn't even mention the atomic bomb in his rescript to the soldiers. Yet he mentions the Soviet invasion.
OK. But the opposite is true in the other discussions / speeches I cited. So an impasse.
It's going to be the hardline elements of the Army and Navy that MUST accept the surrender to end the war. Hirohito needs to persuade them. If he fails, he'll end up being overthrown - or at least taken into "protective custody". Yet Hirohito makes no mention of the atomic bomb in his rescript to his soldiers.
Hirohito didn't convince the hardest hardline elements of the Army and Navy. Hence the abortive coup efforts that (mercifully) failed. For everyone else, he *did* convince them to end the war. And, as I've said before-Hirohito makes no mention of the Soviets in his surrender speech (to civilians, government, soldiers and the world at large) or in the meeting minutes of that pivotal meeting on August 10.
Regarding the Emperor in a leadership capacity, he was, by 1945, an expert at going with the flow. He was but one figure in the government. In theory, the foremost figure, but that wasn't the reality of his position. He was smart enough to know that going against the wishes of his cabinet was a surefire way to see himself isolated away as his father was. The Emperor's thoughts on the issues of the atomic bombs and Soviet involvement mattered a great deal less than those of his cabinet when it came to the actual decision to end the war.
Except for when his words and his words alone settled the discussion. Like on August 10 when he broke the deadlock and instructed his cabinet to seek peace immediately. His decision was the indispensable one then and he exercised his foremost say in the matter directly and with telling effect. Without it, that third bomb probably would have popped off over Tokyo in another 3 weeks or so.
So, in other words, the Emperor was just riding along for most of the war. Except for when he exercised his will, when it was definitive and telling.
I'll also introduce another variable in the discussion. I've heard discussion of what caused the Japanese to surrender-the bombs or the Soviets. But I've not heard anyone sound off on the most obvious reason for the Japanese to surrender. And that was the repeated, grinding, devastating and ongoing military disasters they had fallen prey to over the previous three years. Nearly all maritime traffic, air power, naval power, goods, raw materials, food, etc. etc. destroyed. The depths of their defeat were stupefying. They were laid low on some of their home turf too-there was no escaping their inevitable defeat at the hands of the Americans and the British.
So-what caused them to accept (to them) modestly onerous surrender terms? The atomic bombs? The Soviet threat? I think we have to acknowledge that it's not a 'two horse race'. The devastation wrought by the conventional war with the "western" Allies was a huge part of their impetus for surrender. And it was cited as a precondition by many in Japan at the time (including the Emperor).
So, would Japan have surrendered in the absence of the atomic bombs? Probably. After the Western Allies invaded Honshu and millions perished.
Would Japan have surrendered in the absence of the Soviet menace? Probably. After we popped off 2 (or more) bombs and (maybe) invaded Honshu and millions perished.
Let's say that there was no successful Okinawa or Iwo Jima campaign and that we weren't knocking on their front door, but delivered atomic bombs from Saipan without a likely American invasion being imminent. Let's also say that the Soviets declared war on the same date they historically did. Would there have been sufficient impetus to surrender without pressure of imminent American invasion? I say 'probably not'.
Other than a North:South crossing across Sakhalin and a Manchurian runover, I've not seen exhaustive and convincing evidence the Russians could have pulled off an amphibious landing worthy of the name with their organic amphibious lift capabilities. Other than the loss of southern Sakhalin and Manchuria-and the shock to go along with it-I've not seen any credible rationale for why the Japanese feared the Russians' homeland attack in a vacuum.
