Before I started delving into this topic, I also thought that Russia was just doing this because they are a crazy war machine. But after I looked into the history of it, I can understand better that Russia does have some reasons to feel threatened by NATO. And yeah, if you threaten a country, you can expect conflict.
We should rather go into conversation with Russia instead of ignoring their perspective and continue with things causing conflicts with them.
You've been explained why several times by now and you're just dismissing the argumenst with "well Russia is just defending itself".
Actions speak louder than words. You can justify with all the quotes you want, the point is that reality is before our eyes. I don't sympathize with dictators waging wars for 13 years over much smaller countries.
I'm not saying Russia is just defending itself. I'm saying there was an agreement between NATO and Russia which NATO broke. And since Russia is a superpower, it can start a war, and it can result in WW3. So it's maybe wise to try to make a deal to get peace.
