White Russia Puns

If the Whites win the Russian Civil War and Russia subsequently slides into authoritarianism at some point in time between 1919 and 1938, as every Central, Eastern, and Southern European country other than Czechoslovakia did in real life, and also decides to wage war against Turkey both to acquire Constantinople and to seek revenge for the Armenian and Greek Genocides during World War I, just how successful would Russia actually be in such a new Russo-Turkish War? Also, would anyone--such as the British, French, and/or Italians--actually be willing to militarily intervene in this war on the Turkish side? I presume that the Germans and Americans won't, the latter due to their relatively recent World War I defeat and the latter due to their isolationism. Is this correct?

Specifically, I was thinking of Russia's goals in such a war being the annexation of all of eastern Anatolia as well as all of northern Anatolia, including Constantinople and the Straits but excluding Ankara. Greece can get western Anatolia south of Constantinople and the Straits if it will enter this war on the Russian side. But central and southern Anatolia will remain Turkish and the new Turkey will have roughly similar borders to those of the Sultanate of Rum in the Middle Ages. At least, this will be Russia's goal in this war.

Anyway, thoughts on this?

How would White Russia fair against Nazi Germany in WW2? Would they be able to beat back the Germans or would they be defeated and get lebensraum'd? If they do lose the Great Patriotic War (Eastern European front) what happens afterward? Do they become a rump state or fall into an era of warlordism? I know the White Army wasn't nearly as organized as the Red Army and was much more factionalized to boot. How poorly would they fair against the Axis in comparison to how the Soviets did in iotl?

I'm not very well versed in the Russian Civil war and it's battles, but what if the white armies fled and established control over Siberia? What would happen?

I am from Denmark. We use "Hviderusland" (White Russia) when we describe your country. Just recently our Foreign Ministry decided to switch to "Belarus" (which I personally applaude). I am currently discussing the switch with some friends. They seem to think that the switch is somehow political - either in the context of the current political conflict IN Belarus or in the relation between Belarus and Russia ( беларусь vs. беларуссия). It is my impression that both opposition and authorities in Belarus prefers "Belarus" over "White Russia" when your country is talked about in other languages. And that both беларусь and беларуссия can be used officially in Russia. And by effect, that the issue is not political, but rather a question about a common wish for the more etymologically precise "Belarus".

But, am I correct or IS the question in fact politically charged!
