A very clean and era appropriate piece indeed! Though I'm loathed to enjoy any timeline where the Confederacy is victorious I'm happy to see that Canada is no longer an occupied territory as opposed to Turtledove's post-Great War TL-1911 timeline
Look at it this way: Had the Confederacy won, it would have meant no Jake Featherston. I recall reading on the Turtledove Wiki that Turtledove initially planned the South to win and become more liberal, especially by giving credit to the black soldiers for the victory. Conversely, someone like Gordon McSweeney would rise up in the North, and USA would become more authoritarian.
Indeed MornofVivec the pieces in hindsight were indeed set for such an outcome. I've heard that theory before and having read the books I can easily believe that Mr. Turtledove had entertained the idea of a Southern Great War victory, yet I have a hard time imagining just how the Confederacy and Canada could have overcome the sheer industrial and population gap with the United States in that timeline. It would have been very interesting to know what Turtledove had in mind.
Of course not. Rumania was defeated in 1916 and Russia in 1917. So the Germans had the troops free for the western front. Italian hadn't made it either. They have lost at the Isonzo-River about 15 times hundreds of thousands soldiers. So they were going to loose too. So France and GB wouldn't had hold the western front line. And that is the reason, why the USA got in. Because if the Entende would have lost the war, all goods and money which had been send to the allies would had been lost for the the USA.
