I know Russia has threatened Finland about attempting to join Nato will see a Russian military reaction. Thing is though, unlike Ukraine, Finland is an EU member. Whilst the EU doesn’t have an explicit defensive pact in its treaties like Nato’s article 5 it seems incredibly unlikely that the EU wouldn’t itself respond to an attack on a member state with its own military action.
