Comment on Our Country, Right or Wrong by Kurarun
How come they never bought Alaska? It may have explained that and I missed it.
I made this map ages ago - I may have had an explanation in mind at the time, but I don't remember what it is now. It was probably that the Russians found gold there before they sold it and decided to keep it instead.
Another reason you might consider is that Russia originally sold Alaska to the United States as a way of keeping it out of British hands. Russia and Britain had quite the rivalry and the Russians knew that if it came to war and Britain wanted to take Alaska then there would be nothing they could do about it. Essentially Alaska was a disaster waiting to happen for the Russians so they decided to cut their losses and try to make some money off of the territory. If in this world the Americans were allied with the British then there would be no real desire to sell the territory to them since America and Russia would likely not be on good diplomatic terms.
