"Was it over when the Germans bombed Pearl Harbor?"
I'll have to admit it...the Deutschers were smart. They knew the bomb was coming, so they surrendered before it could be dropped on them (not to mention the fact the Russians had closed in on Berlin).
Actually, Berlin was fully occupied and surrendered on May 1st 1945, while the Nazi government agreed to the unconditional surrender on May 8 1945, when 80% of the Reich in its borders of 1937 was already occupied.
