Therefore I do not think Finland would be a walk-over for the Russians...not to mention what happened last time Russia fought Finland:
The modern Russian army has experience in several different theaters, has experienced and professional leadership, and rocks a small but highly modernized kit backed by copious amounts of older Soviet-era gear.
The Ukranians just got slammed with huge cruse missile attacks -- how will the Fins neutralize that with conscripts carrying skis and rifles?
I respect their bravery, but boldness doesn't stop JDAMs -- they need NATO.
Finland is almost militantly neutral, since that was the original condition to independence in the first place. On the other hand, Russia just voided the Minsk agreement with Ukraine to attack, so...
Imagine being Russia's border neighbor, man. It's seriously stressful.
But if any country is prepared for russian invasion, it's Finland.
Finland a long time ago voided/broke the Paris peace treaty on their own. Basically once the Germany unified in 1990 Finland went "nope we don't like this peace treaty anymore".
If Finland was still following the treaty we would not be allowed to have aircraft that can deploy bombs, mere than 60 planes (including civilian airfact registered to Finland), more than 34k total infantry+border guard, 10k tons total displacement of navy, no sea mines or torpedoes. Finland has gone way past these since.
The only part of the Paris peace treaty we still follow is the no nukes part and that due to signing a separate treaty about not getting nukes in the 70s.
Finland was already able to resist Russian aggression once not so long ago (by European standards), and Russia paid a dire price for attacking in man life. Later, Finland also paid its toll, but in territory.
Both sides learned their lesson. Finland is not going to provoke Russia, and Russia is not going to attach again without reason.
Basically if a Euro country gets invaded and the other countries do nothing that crashes the value of the Euro which would destroy the economies of the other Euro countries. And the non-Euro EU countries have a good reason to follow the same logic as Euro crashing would also destroy their economies.
"If a Member State is the victim of armed aggression on its territory, the other Member States shall have towards it an obligation of aid and assistance by all the means in their power"
