I vaguely recall hearing something similar, with the reasoning being that there was a fear of future hostility enabled by Emperor driven fanaticism. That said, I've also heard that there wasn't really enough time given for a response after the first bomb, and that it was largely a political move to claim they'd offered an initial surrender - and that the goal was always to drop two bombs, partly because they wanted to test out different aspects of their designs.
