Not really if they stay from the bad influence of uncle SAM and behave like good neighbours.
You didn't learn anything from WW2. Their land mass and resources are huge , they can fight and inflict damage for quite some time while fighting on multiple fronts. No other country in Europe can afford that.
That's not how we interpret the agreement in code words or by implication. And it looks like the US, NATO violated the above agreement with Russia by not respecting it's territorial integrity and security concerns.
Do you really want to see dead bodies rotting in the streets of Stockholm? Or your girlfriend, mother and sister raped by Russian forces in front of you , just imagine the humiliation? Or all the houses and cities reduced to rubble?
I am not endorsing those war crimes but they are inevitable in any war. Just look what happened in Ukraine. War is a nasty thing.
Just keep living like a peaceful, progressive Scandinavian nation and stay away from the dirty politics of US and NATO. That's the best thing you can do for yourself.Or your coming generations will regret this foolish decision. Take that as a friendly advice.
At best you can capture the Leningrad region close to your borders , you can't go even close to Moscow. Your landmass and resources are tiny as compared to Russia. You cannot win against Russia with or without NATO. Your land mass is even smaller than the donbas region Russia captured in few weeks. At maximum 4 weeks Russian forces will be in helensinki and Stockholm.
