I'm aware of that, but the inability to develope nuclear weapons means that you can't force an end to the fighting in either theatre, so even if Germany falls as in OTL, you have no way to force an to the fighting in the Pacific,leaving no other alternative but to invade the home islands of Japan, thus fulfilling the challange and extending the war, perhaps as much as 5 years. Also, as I said in my last post, you could probably extend the war in Europe if Hitler gave his generals freedom of maneuver, like they asked for after the D-Day Invasions.
Sorry, I misunderstood - I thought you were linking the two.
In any event, after D-day and the firm lodgement of US forces in France there's really nothing Hitler's generals can do that will delay things more than a few months - the Allies have simply too much of an advantage in men and material at this point. As for Japan, five years??? Surely you jest.
With much of the population de-housed, massive infrastructure damage and breakdowns in distribution, plus mobilization of the population to die suicidally, the winter of '45-'46 is going to be bad, very bad: when you add in US plans for destruction of the Japanese food supply with chemical and biological weapons, expect mass famine in '46. Even if the Emperor doesn't call for surrender in the face of deaths that make the Hiroshima bombing look like a case of acne (assasinated? Killed by a misplaced bomb?), Japanese society isn't going to make it through the winter of '46-'47 as an entity coherent enough to carry on anything like organized warfare. There might be some guerrila attacks for a while yet, but anything that can be called a war is unlikely to go on after 1946.
Now, if we have no atom bomb, and the Germans manage somehow to break the back of the USSR '41-'42 so the US has to invade Fortress Europe with little or no help from the Red Army or Instant Sunshine, I can see things grinding on until '47 at least...
best,
