Since this is an area that doesn't seem to get more attention, what would California (and the rest of the West Coast, for that matter) have looked like under Russian colonization without the Spanish/Mexicans being there? What happens if the US still exists & decides it wants that territory?
Russian colonization of Alaska
1848 - gold found in Caliphornia.
1849 - USA/Russia war over it.Russia could send army there and beat USA,what next? /they send their army to crush Hungary the same year - so,not much could be send.But USA have maybe 10 regiments,they would be defeated./
Would England and France support USA ,or Russia?
We could have Crimean war in Caliphornia,too.
But,if USA would be saved by brits,they would take something for it - for example,Oregon.
The same goes for french - maybe they take Alasca,or divide it between them and brits?
England in this scenario could keep Vladivostok.
