This is just fearmongering based on XIX century thinking. There is no expansion drive by default, however there are couple strategic "red lines", which, when crossed make Russia react aggressively. 1. Hostile military block on the borders (expansion of NATO or any moves that may be treated as towards the expansion or challenging the status quo, as in Ukraine with Crimea). 2. Status of Russian population and Russian language (Georgia in 2008, Ukraine - Donbass, Baltics - low intensity information war). For the neighboring states they are the keys to their own security: addressing those fears of Russia by diplomatic means, those countries can bring more peace than arming themselves against the invasion.
