What if the US entered the war (presumably provoked by earlier USW or even more aggressive sabotage ops) in 1915 or 1916?
Would any movement forward in time of participating AEF forces (by X months), and the casualties (by Y thousands) resulting from that earlier engagement, be "offset" by the war being an equal amount of months shorter and casualties not being suffered by the Americans in what were the "back-end" months of the war?
Or will America spend more time, lives and money on WWI, with a negative return on investment, with Germany probably being defeated sooner than OTL, but not in full proportion to the this greater, more precocious US effort?
Flipping the question around:
What if US DoW and especially engagement of the AEF in force was *slower* than OTL but still occurred. How would that work out in terms of net losses an the timing of armistice day?
