I saw a military expert say Russians historically care little gaining land as a goal in a war. Their goal is to slaughter the enemy as much as possible, which they’ve been doing quite successfully
It is not the Russian way, but the proper way of making war.
The NATO doctrines are basically based on German teaching, or to put it correct on what the former Nazis made up about their doctrines.
The fact is that the Nazis lost WWII and so does NATO in every war ever since.
