Russia/USSR didt participate the the Treaty of Versailles.

Don’t forget the two countries signed Munich agreement with Adolf Hitler in 1938.

Dont forget the two countries signed Munich agreement with Adolf Hitler in 1938.
They also signed an alliance with Poland, and declared war on Germany when it invaded.Both Germany and the USSR wanted Poland . . . and much more. Including each others territory. After the German blitz of France, of course, Stalin knew a lot better than to pick a fight with the German army. Having purged his officers, Stalin had good reason to know that his army was not well led.
Only the German invasion of the USSR made any agreement between Stalin and Churchill possible.
