McKinley Kantor wrote a book, oh, back around 1962, entitled "If The South Had Won The Civil War." It's still a good read.

I've always wondered what would have happened if Hitler hadn't turned Guderian's panzers south for the oil fields and had let them take Moscow instead. Or if he'd let the German 6th Army retreat at Stalingrad.

Probably nothing much, other than prolonging the war a while longer. Stalin was set to bolt from Moscow and run to the Urals, for instance. But what would have been the longer-term impacts?

Or suppose that Japan had been truly serious about taking the Aleutians and Alaska?

Or Quebec seperates from Canada and the US, to preserve the strategic St. Lawrence Seaway, allies with Canada and invades Quebec? Or Quebec seperates the the Maritimes sue for Statehood since they are now seperated from the rest of Canada?
