Who sides with whom in White victory scenario:
UK-fears Russo-French domination of the Continent. Wants strong Germany as counterbalance. Try to enforce German-Polish reconcilliation (propably unsuccesfully).
France-wants Germany as weak as possible, so we'd have break of French-British alliance. Seeks for alliance with Russia against their common rival... UK (which happen to be German ally ITTL).
Russia-has resentments against Britain. UK supports independence of Baltic and Transcaucasian States (more important areas for Russia than troublesome Poland) and is Russia's traditional rival in Central Asia.
-Poland and Czechoslovakia sides with France and Russia due to lack of better options. Romania and Yugoslavia too due to being allied to Czechoslovakia. France wants Germany weak so would still support Poles and Czechs against Germans
-Baltic States, Italy, Turkey and Transcaucasian republics side with UK and Germany due to fear of Russia and in the case of Italy-dependence of imported coal and rivalization with France.
