What the debacle of the West's last Russian invasion teaches - also about Ukraine. There is much to learn from the fight against the Bolsheviks for today.

The Western intervention against the Russian Bolsheviks is an unmentioned yet instructive mistake. There are some exciting parallels to the Ukraine War, comparing motivations, allies and ideology. Conclusions can be drawn from them that cast an optimistic light on an intervention. The intervention failed, and if one looks closely, today's intervention in Ukraine may seem similarly hopeless in the face of a determined Russia.
