Hnau's No Lenin TLs are really great regarding no Soviet Union although it also lacks a major civil war. However it does deal in part with a democratic post-war Russia.
Nazism will suffer countless butterflies without the Soviet Union floating around, for one the left will be a far stronger oppenent to any far-right force.
A 'White' Russia with Kerensky in charge will probably have a strong military (a few coups and revolt-crushings will be expected) in terms of influence.
