it seems everyone is quick to point out all those disadvantages the japanese and germans faced late in the war and use that as some sort of excuse whey the allies were able to bully them around. but it was the same scenario in reverse that let them enjoy all their quick gains and easy victories....but you dont really hear that as an excuse why they were that successful early on.
Well, this is not quite accurate.
The Japanese always had inferior radar and radio communication through out the war. Even at Midway, their planes had been flying for a long time without proper replacement and maintenance, they were even short of their full complement of planes.
I'd say that in the Pacific theatre, the US was in pretty good shape with it's carrier planes at least from the start, and from Mid 42 on I wqould not see any long term logistic problems they had.
Fuel was a major issue for both the Japanese and Germany, for Japan almost from the outset, for Germany by mid 43 I'd think. The US never had fuel shortages,other than perhaps very temporary issue with supply keeping up with the advance.
This fuel issue for Japan and Germany helped create problems for them with training new pilots. and one thing the US never had t worry about was having a war free zone for their pilots to train in - by late 43 in Germany, later in Japan, the skies over their homeland were not safe for training.
The problems Japan and Germany faced vs. the allies are not equivalent to early war allied situations. Now, it may be a bit similar to what minor countries had as disadvantages early in the war, but that's about it. The Allies had a few disadvantages that the Axis did, but certainly not all or even the majority of disadvantages late war Axis powers had. Or, if they did have these problems, like US in the Philipines in the early going, it was a rather isolated and short term issue.
the axis wouldnt or couldnt escalate their manufacturing and training to exploit their advantage and stay ahead whereas the allies were able to pick up the pace and overtake their foes.
Could not is probably the correct term. The combined Axis powers, including Italy were about neck and neck but still behind US manufacturing from the start of the war til abut 43, with the US going up about 2/1 in 43-44, and even worse for the Axis in 1945. And that's only the US, not counting Russia and Great Britain, and China for that matter where the Japanese invested and lost a lot of their army's energies.
Aircraft production was about 620,000 for the Allies, 210,000 for the Axis.
In crude oil production the Allies had better than a 2-1 advantage.
This production disadvantage IMO is well illustrated in the Navies of the US and Japanese. Japan was fighting WW2 with a navy predominantly from the 1930's, their biggest period of buildup (plus older vessels), will the US fought the war with ships built in the 40's due to their industrial might. This period saw significant advancement in ship design, making the Japanese vessels decidedly old fashioned compared to their US opponents.
It's pretty simple - the Axis powers were pretty well doomed in World War II once the United States entered the war. It would have taken almost a miracle for the Axis to have achieved a victory unless they were able to get the Allied powers to sue for peace early, which I do not believe they ever would have done.
We can speak all we want of heroism - but in the simplest terms, the Axis powers were out produced.
