So will this be another unprovoked attack when Russia moves to protect itself?
Russia isn’t stupid enough to attack.
Won’t be an attack. If Ukraine was in NATO the Russians would not have attacked there either. This is the purpose of a defensive alliance and exactly why Norway and Sweden are joining. Putin miscalculated badly if he thought that attacking a sovereign neighbor would prevent other sovereign neighbors from joining a defensive alliance.
Yes, since NATO is not attacking Russia (yet).
“So will this be another unprovoked attack when Russia moves to protect itself?”
Are you implying that Russia invaded Ukraine because it had nuke missiles?
