Someone probably has , I know there have been books like that speculating on what would have happened if WW2 never took place . I agree , the North South thing is pretty much gone , but the divides go further than you think , urban / rural is the least of it . too many culture mixes that dont play well with each other , religion problems , liberal/conservative , freedom / socialist , etc . This nation has not been this divided sense right before the first civil war started . Something is going to happen .
