That is one line of speculation, and an interesting one.

Another, less profitable, asks: "Could the Allies have won without America ?" The answer I have heard most commonly given is: "Probably yes, considering, especially, the disintegration we now know to have been going on in Germany, and the cumulative effects of the British blockade.

But it would have taken at least six months more fighting, the loss of thousands more precious and irreplaceable lives, and the squandering of vast additional wealth in the bottomless waste of war." Thank God, we did not win without America! The effects, the far-reaching effects, of America's intervention, of her comradeship in the field of suffering and sacrifice with the free nations of old Europe, are only now beginning to show themselves above the horizon.
They will be actively and, as at least the men and women of faith among us believe, beneficently at work, when this generation has long passed away..
