> Russia is too threatening to upset your security guarantor. Come on stop spreading this dumb western propaganda, Russia isn't threatening anybody in western Europe. They took Crimea back and sabotaged Ukraine because strategically they can't afford to have yet another NATO country right at their doorstep. They're not going to invade Poland any time soon (what for anyway?). They're not crazy nor blood thirsty. This…
They won't invade Poland or Baltics because those countries are in NATO and EU and it's way too risky. Russia seems pretty involved in all the hotspots lately including starting a war in Ukraine. Very likely same fate would be for Poland and Baltics if they didn't protect themselves with stronger allies. And even if current Russia is not interested/capable to cause trouble to east EU - that doesn't mean it won't chan…
It started with very active meddling, spending copious amounts of money, into the internal politics of the country. It should also be noted that much of that money went to ultra-right-wing militant organizations, who have zero respect for democracy or freedom. Essentially, the USA bought itself a (fascist) private army to take control (or at least try to) over the natural resources in East Ukraine and Crimea. Russia responded rather predictably to that.
Some might even argue that they had every right to do so. I'd love to see Americans react, if Russia were to sponsor some kind of anti-US militia in Alaska, that would subsequently take control of state (military bases with missile launch facilities included). I'm pretty sure that US citizens would call that for what it is: an act of aggression.
No, the reason Russia doesn't invade Poland or the Baltic countries isn't because of NATO. Ironically, if those countries are at risk in any way, it's probably rather because of NATO. NATO (and its members) keeps insisting that the organization is defensive in nature only, yet its actions tell a rather different story (and it has done so for a long time, at least since the '90).
