The russian border was last challenged by hitler and before that by napoleon. Anything after that is just been being pissy about everything.
> Beginning with the reign of Ivan the Terrible in the sixteenth century, Russia managed to expand at an average rate of 50 square miles per day for hundreds of years, eventually covering one-sixth of the earth’s landmass.
Ah, yes, when it is a Western border at risk it is totally fine, it's not fine if that is a Russian border.
Hypocrisy.
