It is revealing of both the Russian mindset and the Western European mindset. Before WWI, the Western mind set was "no one will go to war, we're all making too much money at peace." No one accounted for a German Kaiser with an intellectual capacity that prefigured the current potus. I believe Europe still has this same mindset and is struggling to come to grips with the idea that Russia could make so much money and be happy in peace if it chose to do so. They are just waking up to the fact that they have created a monster on their own doorstep and they can't just stick their head in the sand and pretend it isn't happening.
But the Russians just don't see the world that way. They are of the mind set that they are either invading or getting invaded. They either control or be controlled. There's no middle ground where there is a good faith meeting of the minds, exchange of goods and ideas. Diplomacy is a zero sum game. This is especially true of Putin the man. You're either screwing or getting screwed. That leaves no room for individual growth - whether intellectual or economic. It leaves no room for the long term development of resources of the national good. And really, it doesn't leave much room for peace. They must be ruthlessly defeated. Otherwise, we're just asking for more invasion.
