It might have been good to alert the Wehrmacht leadership post-Bagration of the fact that the war was already won. As I seem to remember they fought for several months after Dresden and all the firebombings, though at least part of that was the demand for unconditional surrrender made by the Allies. It was completely without precedent and not the most brilliant move they'd made (and ironically had FDR lived longer Downfall would have happened after the nukings as FDR meant unconditional surrender when he said it).
