I did not want to turn this into a lengthy discussion which is why I deleted my last post. By 1942, the fact that the allies would prevail was really no longer in doubt; most historians would agree to this (see Gretz's comments). The way the war was going to be prosecuted was still a question and that doesn't mean it was going to be easy and that the costs were not going to be enormous and that it would it not take time, but excepting a complete loss of allied will which was not going to happen, the outcome was certain. The resources that could be thrown against the axis were just too overwhelming.aknowledgeableperson wrote: (1) Saying that unconditional surrender was the end point does not lead to say the outcome was not in question. It says that we, as a group, are in it to the end. Say France could drop out once the Geman army was out of France instead of to the end or England will crease its efforts once it feels that Germany is no longer a threat.
(2) If the allies felt that Normandy was a done deal then why the concern about failure expressed by Eisenhower? Much can go wrong during that large of an operation and if it did fail it would have been many months until another invasion would have taken place. And again, looking back one could say Germany was done but during the time there were many that were still concerned about Germany's capacity to wage war.
I did not say that the allies regarded Normandy as a done deal. I am sure there was doubt and they knew it was going to be costly. My point is that the Germans simply did not have the capacity to throw the anglo-americans back into the sea. Read the historical accounts of Germans who served in Normandy, daylight movement was nil impossible; they simply could not mount effective offensive operations and failed miserably when they tried. By the time of Normandy, the Soviets were rolling in the east. They destroyed much of the German Army in east in the summer of 1944 and the way was open for the Soviets to roll through Poland and into Germany. The only thing really in question regarding the outcome of the war (although not realized quite yet by the US) was how much of Europe the US and Britain could salvage from the Soviets. This is why Eisenhauer eventually diverted troops away from the Berlin axis in 1945 to cutoff the Soviet advance towards Denmark (the US was alerted by the Swedes that Stalin wanted to bring Denmark into the Soviet sphere of influence in the post war world).
