The USA would have 39 states and the CSA 11. North America would have 4 countries instead of three. Not much difference in that regard.
Well... Confederates claimed 13 states plus Oklahoma and New Mexico/Arizona, so that's 16 with the USA down to 34.
Then there's West Virginia, Confederate victory would keep that in Virginia, USA now 33.
And while we're at it, victory would also mean Maryland and DC -- Confederates 17, USA 32.
But wait... let's talk about the Mississippi River under strict Confederate control, closed to commerce from "unfriendly" Union states but open wide for all who respect Southern rule -- another dozen Union states & territories, from Ohio to Nebraska suddenly become "neutral" just as Kentucky had tried to be in 1861.
And maybe half of them consider applying for Confederate statehood.
Now I count Confederates 23, Union 26 states.
And why would California & other west-coast states want to belong to a rump Union that was clearly failing to inspire loyalty from its own citizens?
So California declares its independence taking the mountain states with it and now we have a Union of the Northeastern states and maybe, what, Michigan & Wisconsin?
By the way, none of this was ever intended by central_va, who only ever wanted his Confederacy to be left alone by those mean old Yankees.
But DiogenesLamp knows full well what I'm saying, and agrees with me 100% on this point at least, if on nothing else.
