\1 In real actual history, the US didn't developed a working nuclear weapon based on UK provided designs until after the German surrender.
So in real history there was no chance to "glass" an active EU war zone during WWII.
\2 In the GP's fantasy history in which the US left Europe alone to deal with the Nazi's on their own, the MAUD folk would have never passed on their research to the US and the US would have wallowed in their belief that nuclear weapons were impractical and continued on messing about with atomic power from big piles.

I'd be happy to see X gone. You won't be missed.
