Ladies (maybe?) and gentlemen: what is the last possible moment to save Russia and have it turn out well?
That can mean some faction of the Commies managing to reform Russia without mass killings and maintaining some kind of relationship with the outside world.
Or Kadets and Grand Duke Michael Alexandrovich turning Russia into a functioning democracy with a constitutional Tsar.
Or Kerensky (or analogous figure) pulling something out of his nether regions and some White Russia that isn't terrible.
Entente or Central Powers early victory?
Even afterwards, the most obvious and difficult issue is economic reform. Without Stalin and forced industrialization + collectivization of farms how does Russia manage to transform into a peer European economy without mass peasant revolution?
(As usual, lately, I'm asking in regards for my Futurist Manifesto timeline. Lose or win, I'd like to see Russia turn out well, but the needle threading I have at the moment is… iffy. So, in hopes someone has something I missed: the floor is open.)
