It is not a sarcasm: thanks to a well intentioned but too trusting politician, NATO moved to East and Russia has to fight for survival against vastly superior opponent.
If you are interested, we could look at the map, compare some numbers (weapons, population, media control, the number of countries bombs, etc)
If you are interested, as a Russian native speaker who lived in Ukraine until 2003 (and has been there as recently as July of this year), I can tell you how the "fight for survival" you speak of is a load of propaganda bollocks, going from primary sources in Russian.
