Invasions of Russia were not because West wanted to invade East, but because couple of lunatics wanted to control the whole world and Russia was perceived as an obstruction to that. Your theory of West not learning enough from invading Russia could also be reversed back. Russia should really learn from invading other countries. Starting from Korea some 100 years ago, through Afghanistan etc. I have one word for the ^. Paranoia.
...The West could be perceived as slow to adopt this lesson, given the number of attempts in the last few centuries. The problem for Russia is that even spectacularly unsuccessful invasions have been extremely damaging and costly to defend. It seems an outmoded way of thinking though, to me - but perhaps this 19th century mindset informs the perspective of the Russian leadership?
