Had Kaiser Wilhelm been allowed to remain on the throne, we would not have had to put up with a certain Austrian corporal twenty years down the line.
WWI was one war the US shouldn't have intervened in. Blame Wilson's ideological fanaticism on "spreading the goddess democracy" and his (and his state departments) slavish Anglophilia.
Woodrow Wilson's mother was born in Carlisle, England. Maybe the "natural born citizen" rule needs to be amended--only persons can be President if
both parents were born in the U.S. Wilson's Anglophilia may have influenced his handling of the war.
Of course the conduct of the German government gave the Brits a lot of propaganda fodder (burning of the library at Louvain, etc.)...plus killing civilians both in occupied territories and on ocean liners.
