> At the same time, US is expanding NATO with more and more countries close to Russia border. Why is it so difficult to figure out this makes them very uneasy? Wouldn't some kind of response be expected? Why would US be surprised by it? One of the reasons could be that US and RF are very asymmetrical players in the game. The structure of control in RF is less reliable, to the point of having arguments (not in the Kremlin, of course) of passing nuclear arms to US (!) to avoid dangerous scenarios. The intents are also different, modern RF power is mostly interested in material gains rather than strategic development. Abilities are different - RF can't always adequately answer to some voids left.
