> Then we really didn’t give them enough time to process the enormity of what had happened and surrender. The whole point of using both bombs was to demonstrate not only that it had been achieved but also that it was easy to repeat indefinitely, since the consensus among German and Japanese scientists seemed to be that atomic bombs were impractical to implement in a reasonable timeframe. Had only one been used, or so the thinking went, the suspicion would have been there that it was a one-off thing. Moreover, by most accounts, use of the atomic bomb didn't really change the behind the scenes politics of the Japanese leadership, though it may have accelerated things. The faction who wanted to sue for peace continued to do so and the military continued to advocate continuation of the war even after both bombs were used.
