Also Up with the Star . . .
is a good TL, but I think it is not what you mean, because Britain and Italy are on the side of Central Powers, and France, Russia, and Austria/Austria-Hungary are the 3 Entante powers. It even makes sense historically, because Italy and Germany were allied against Austria and Russia since 1866. Britain did oppose Russia over India in the Great Game, and was paranoid of losing India to Russia. And the U. S. allies with Britain. So the “Central Powers” win the war, but you don’t get an invasion of Belgium. Very interesting TL, Up With the Star. It makes sense every step of the way.
