Are you saying that the Eastward expansion of NATO or inclusion of Ukraine into NATO were none of the issues when the current war broke out?
If Russia is scared or insecure, that's on them, not a valid reason to murder others, NATO is a defensive pact
Listen to what Putin says in Russian, the war is about Making Russia Great Again, a conquest of empire. He miscalculated and Russia is in the worst place it has been since the fall of the USSR. Their future does not look bright either.
