I think butterfly effect is bullshit.
And it is Bradbury.
I stand corrected on the writer (I was sure it was Asimov. Huh.)
Second, that is your opinion. I would say however that the butterfly effect very much fits the common perception of how the world works. To take your example: the Russians retaining Alaska will have a number of effects upon the global balance of power, but it will also have an uncounted multitude of smaller effects. For example: the money the OTL US used on Alaska will instead go to other uses. It migh slightly reduce taxes, which will allow a man to marry and have a child that wasn't born IOTL. It might allow for a larger standing army, which will result in a man not being discharged and thus not meeting the love of his life. You could reverse both these scenarios in Russia for the government
not having the money. And then you have all the other, unknowable differences, causing other differences, stacking up decadeafter decade...
I personally find it hard to enjoy a TL that doesn't take these into effect. But c'est la vie.
Except of course that the author knows all these "unpredictable" consequences. And again if one butterfly does not pollinate those flowers another will. The bird that would have eaten the butterfly will eat another, or not. History going in completely different direction is no more plausible than history goint in the entirely same direction.
And the butterfly that is eaten rather then pollinates then it gives the bird the sustinence it needs to survive. It then trips a passing stable boy, resulting in him needing to wash his clothes and thus conceives five hours later, resulting in a different sperm and a totally different son, who in turn will act differently then any of the other sons would have...
We're talking about a new British colony here, so the butterflies would go straight to the British Colonial and Foreign Offices. A certain young dandy by the name of Lord Randolph Churchill is currently sitting in Parliament. Do you really think he'll be totally unaffected?
No. But it is about the limitations of British Empire. If Russia retained Alaska into 20th century I see little reason for that piece of Russia to be severed from it. I can see that UK could ahve taken Alaska, but it would be rather unprofitable acquistion.
So in other words, you've made up a scenario...to make a point.
Stalin is attacking Alaska because as Gasudar of Russia he cannot leave any piece of the Motherland unattented.
Here's the thing about the lands in Eastern Europe that Stalin reclaimed: they had strategic value, valuable resources, were traditionally coveted by Russia, and
were close to the Soviet heartland. And even then, Stalin only moved when he had a chance to move safely, without antagonizing a major power. There aren't sufficient forces in the Far East to invade without either leaving the Japanese border unguarded (musn't leave an opening for them to get revenge) or sending troops in the west on a months-long, demoralizing trek to Siberia and leaving the way open for a German invasion.
Stalin was a statesman. A brutal, paranoid, repressive statesman, but a statesman. He grabbed what he could, but never actually started a war with a major power. It doesn't seem slightly out of character for him to randomly declare war on
two major powers (I'm not seeing the Americans not joining in, assuming they weren't selectively butterflied to hate the British too).
Thanks for reading recomendation, but I stopped reading for exactly those reason. A lot of handwaving under guise of "butterflies" followed by the future of TL being decided by authorial fiat. At certain point AltHist scenarios stop being "what could happen", but start being "how can I justify a British Empire on which the Sun Never Sets?"
So you're backing up on the dig about experience?
Also, has it ever occured to you that it may be just as much handwaving to force history on the exact same track as OTL? You seem to be dictating the setting of this scenario so that it is maximumly bad for the British.
Also, in which of those TLs do you think the sun is never setting? DoD has the Empire traumatically destroyed by German invasion, while LTTW doesn't have a "British Empire" in the OTL sense at all. Both seem, on the whole, extremely well-thought out and unwankish to me.
