Let's say that U.S. President Woodrow Wilson cuts off U.S. loans to the Entente in 1917 and Germany doesn't resume USW that year--thus allowing Germany to win WWI by default once the Entente begins experiencing severe financial problems and is no longer able to fully fund their war effort.
How much stronger and better off would Germany be right now in this TL? Specifically, I am thinking in terms of its economy, total population, et cetera.
Any thoughts on this?
