The basic premise of this comes from how Czarist Russia offered their support to the Union near the end of the American Civil War. So what would have happened if either France (as I don't Britain being willing or able to do so) had given the Confederates a bit more outright support, to the point that the war lasts a bit longer and Russia had been given the chance to help the Union or that Russia had offered their support some time earlier, to the point by the end of the war there's a firm friendship and alliance between the two countries?
Just how would this have effected the world?
