Yeah, this argument about the NATO threat is repeated ad nauseam because it superficially sounds like a reasonable justification: "they just had to defend themselves".
But even if that was true, Otto von Bismarck said it well: "Preventive war is like committing suicide out of fear of death".
Imagine an alternate universe where Ukraine joins EU and NATO and now russia faces a NATO "wall" on the west. In this alternate universe where Russia didn't initiate an aggression, the public opinion of most european countries is not particularly interested in military spending.
Compare that with this universe; the city I live in in Italy is going to build a new military base and while some people will certainly complain, the backlash won't come close to a pre-war scenario. Now even the population feel it that the rules have changed.
Effectively Putin has armed Europe to their teeth. What a perfect 4D chess move to protect Russian safety.
And seriously, I yet have to understand what is the threat that "NATO" would pose to Russia. What should they be worried about? Are they afraid that one morning NATO will invade Russia? What for? This part of the scenario is so embarrassingly hand-wavy, seemingly imbued only of reverberance of a distant past.
Or is it that Russia be afraid of Western values infecting Russia? In that case, what difference does it make how many neighbouring countries are NATO members? You can just decide to make your laws and your policies and live your life according to your chosen lifestyle (if your citizens so wish)
Or is it perhaps that Russia used to be a super power and now it isn't anymore. The greatness past now must live again. Let's reclaim our destiny and all this bullshit. This not how civilised nations should be run. This is barbaric and should stop and sadly the only reason humanity has to put up with it is the nuclear arsenal.
