Great War

As with OTL, WWI was refer as the "Great War", but there no indication that this term will or will not change for World War I after WWII as it did in our timeline. Like OTL it was fought between the Entente and The Alliance. But the addition of the United States to the Alliance and Confederate States to Alliance created an American Front.

Aftermath
Contrarely to OTL the Entente was beated in 1917, Germany and U.S standed as the leading world powers, but the frustrations at the loser side only helped spark another conflict.
