ZachScape made a rough draft of a map on a Russian dominated Philippines, and it does include Alaska, Yukon and BC, along with parts of Alberta, NWT and Saskatchewan. It's on my thread. I believe if the USA lost the Civil War, they wouldn't be able to buy Alaska, like they did in OTL. Or if some advisor told Alexander II not to sell Alaska and they found gold there, then it would be plausible.
There's a novel on an ATL where Alaska is kept within Russia's possession, called Russian Amerika. If you would like to discuss this further, you can leave your comments on my AH Challenge: Russian Dominated Pan-Malay State or just the Philippines.
Let me comment here first before your thread to settle something. There was never any USA in the map I made. In the map I made, the British lost TTL's version of the 7YW/F&I War, which in its own will require quite a bit of work to make that plausible. Now, with the British loss in the war, the Dominion of America is created as well as the British Colony of New England.
With the French focused on colonizing their new found territory, the Russians were able to explore and claim vast amounts of land that nobody else would even care about.
Eventually, an Oregon type dispute is created between Russia/France and Spain. Russia/France wins, France gains a Pacific Port, and Russia gains the territory they wanted leading to Northern California.
So it's not that Russia is able to populate all these places all too well, but instead France leaves them to their own devices. And the populations they would get would almost certainly be a Manchu/Sino majority.
Hopefully this answers both threads questions, and is not a hijacking. In order to keep it from being one, I would appreciate if any quotes from this post are taken to Sibirskaya's thread.
