ok, D-day was very risky, not only germany could stop the invasion, but weather could had turned it into a disaster, if by any means it had failed, would nazi germany had survived the war? thanks to the comming of extremely new technologies such as rockets, jet engine, and developing of incredible new tanks such as teh tigerking (not sure) would had any good? hitlers health was deteriorating, and a new leader would had been posted who was not as stupid..........and had some idea of waht was happening, or would the allies had won anyways from an invasion throug italy? and teh red advance?
