If you've read the History of the German Assault on Russia, the SS Einsatzgruppen did terrible despicable things to Soviet citizens and soldiers alike...Berlin was 'pay-back' time. - Ahanswurst is correct that there wasn't a need to A-bomd Germany, obviously the B-29/Lancaster delivery-aircraft factor is really an opinion thing...I believe the Lancaster COULD'VE done it , the B-29 went and did it, in Japan, but wasn't anywhere near ready to do it to Germany, at the time ...
