I'll explain it a little better too
The highest number of factions to be at war with each other is: 7
-USA
-CSA
-AUS
-PSA
-Canada (intervention) with puppet New England if it got created
-Mexico (intervention)
-Puerto Rico (if it revolted)
Countries that will be created but (mostly) won't fight: 1
-Hawaii
Hawaii could fight if Canada intervened and it joined the Entente. Also if I remember correctly, other entente countries could also join Canada in the intervention as I have seen French Republic naval invading in Texas
There's a lot to explain but I think that's enough
