This would be the first illustration of literally
Yet another what if - what if US command decided to drop the bomb on Tokyo and not on Hiroshima.
Let's add that the bomb is dropped and Imperial family (together with the Emperor) dies in the explosion.
This would be the first illustration of literally making the rubble jump; Tokyo had essentially been destroyed by the previous "conventional" bombing campaigns with HE and incendiaries.
Which demonstrates, of course, the significance of the destruction of Hiroshima and Nagasaki; as it was, by the time of the atomic bombings, there were only about four Japanese cities (the other two being Kyoto and Kokura, IIRC) that were even intact enough to warrant being listed as targets...
And yet the Japanese chose not to surrender, not after the Marianas operations destroyed the IJN as an offensive force and provided the US with the necessary air and submarine bases for the strategic bombardment campaign and sustained commerce-destroying campaigns in Japanese home waters; not after the IJN was destroyed as a defensive force in the Philippines; not after the IJA's largest field army in the Pacific was destroyed on Luzon; not after the IJA's second largest field army in the Pacific was destroyed on Okinawa ... and not even after all but four Japanese cities worth the name had been destroyed by aerial bombardment even before the atomic bombings.
It's almost as if they were not thinking rationally, or something.
Best,
