Finland was historically part of Russia. They have been neutral for years and have avoided aligning themselves with anyone. They have an 800 mile long border with Russia. Putin has form now for invading countries he'd like to have back in the USSR. If I was Finnish, if be joining NATO too, and if Putin complains, well he knows who to blame.
Anyway, Turkey may well block it.
From what I've been reading over the course of the Ukraine invasion I doubt that Putin has any thoughts of invading Finland in the near future. His forces are stretched in Ukraine, he is using young and poorly trained conscripts mainly as cannon fodder and to bulk up the numbers on the ground. It is suspected that he daren't call for mobilisation of his remaining army because firstly he hasn't actually declared war (it's still a 'special operation' and secondly, mobilised troops would have to concentrate through Moscow and he may fear an attempt a t a military coup as the army can't be particularly pleased with him at the moment.
He must be painfully aware of just what a paper tiger his army has turned out to be...
Additionally his 'conventional' weaponry is old and poorly maintained as a result of corruption at many levels. There is a question over his ability to increase weapons production because sanctions are depriving him of western made components which he needs. Is he being supplied from elsewhere,? It doesn't look likely. China is standing back from him and where else could he turn?
He is old (ish), and by many accounts, probably terminally ill. He doesn't have much time to prepare to be fighting in more than one European theatre.
He has apparently affected indifference to Sweden and Finland's plans to join NATO.
So I don't think they are in any particular danger of being invaded. OTOH it sends a 'Don't even try' message...
Nor do I think we're on the verge of WW3 (not relevant to the quoted post I know. Just my opinion)
