In the rear-view mirror perspective get warped at time.
Molotov-Ribbentrop including the secret protocol appears as typical eastern-Europe hyper-realistic reaction to the Munich agreements in 1938. The desired "united front" came later when there was willingness to have one as well in the West.

Rear-view mirror morality. The only available perspective in the West although it's often turned the wrong way, used as looking glass towards anything East.
