Falkland is British territory. Every sovereign countries are prepared to fight to protect their territories, no matter how insignificant they seem to be. Kirin, Senkaku, Spratly. Ukraine, on the other hand, doesn’t belong to Russia. If Russia invade Ukraine to prevent NATO at their border, they now have a much longer of that border to protect. They also have to spread their force to fight the insurgency within Ukraine. Finally, Finland now decide to join NATO because of the invasion, exposing Russia to a much bigger threat. I doubt Russia didn’t see any of those scenarios before they decided to invade Ukraine, so no, it doesn’t make sense to do it because of NATO expansion. Rather, Russia consider Ukraine part of their influence sphere and can’t accept the fact that Ukraine’s people don’t want to be under their manipulation. Russia want to go back to their glory past. Not to mention the resource Ukraine would bring to the empire. NATO is just an excuse.
