WI: The American Civil War became WW1 but ended in a Confederate Victory?

So it's pretty well known that Britain and France almost entered the American Civil War while United States had support from all across the world even among members in the homeland. Most notably Russia and the Ottomans. If France and Britain did enter the war who would join the US faction and CSA Faction beside Britain and France? What would the War look like in Europe and the Americas? What would the world look like it this ended in a Confederate Victory? What be the Politics in the USA and CSA? What would the Treaty look like for (ITTL) Post First World War?
