I presume the Mutual defence clause of the European Union played a role as well.
The NATO (and denazification) "arguments" are just bits of rhetorical flim-flam to soften and confuse the opposition, basically.
If someone came and slapped you in the face but:
a) he is 90 kilos full of muscle
b) he is a lanky 55 kilos
would your reaction be the same ?
it is not a perfect analogy of course, but I want to point out the flaw in your reasoning.
Are you here for hacker news, or for spreading propaganda because you're on a payroll ?
Why are most of his comments about russia (if that's the true even): perhaps he is interested in the subject and has a nice attitude of only speaking about something he is knowledgeable in. Or maybe the subject of russia is something he find very emotional and feels an urge to speak about it.
Let me mimic your rhetoric:

According to Hitler (as well as Putin, who really justified Hitler in that same interview) Poland made him start the war by refusing to give up Danzig.
Any dictator in history had a cover story before starting a war. And by spreading such a story you become a part of the aggressor's propaganda machine.
