That does not answer my question and is actually another reason why there won't be another Russo-Japanese War in this scenario.
It fully answers your question to the Sith running the IJA weakness was a gilt-edged invitation for them to enter your country, take your stuff, rape your women & wreak up the place.
Given the fact that ''White Russia'' would be an unstable basket-case, with no legitimate central government or popular support. Japanese adventurism in the Far East is almost inevitable.
Still ''White Russia'' wouldn't be quite as bad as China under the KMT/Warlords, but it wouldn't miss by much.
