If you can't see the geopolitical implications of NATO from a Russian perspective I can't help you. Are you all ignorant to the fact that countries have their own spheres of influence or is that exclusive to the West? Nato have been significantly strengthening their presence to the East since the war, as evident in that map. Russia isn't happy with this and that's been the rhetoric for a couple of decades now, yet it's continually crept East. Stop being will fully ignorant to this and understand what could happen if you continually poke a bear.
Don't wind me up, I'm no Russian supporter are certainly not in favour of this conflict but don't act like the West, particular the US haven't a history riddled of conflicts that launched on greatly flakier or even damn right illegal justifications.
