Ukraine

Please show me where I make just a hint about that, I have not written ANYTHING about the Finish defense capabilities.

Ok:

Finland could be overrun before a decision was made in EU to even do anything.

"Our lacking ability to supply Ukraine without USA". It's not about the lack of ability. It's about Ukraine not being in EU, so direct military aid, and especially troops is harder to send. Our militaries aren't designed to be overflowing with equipment we can just donate away, so it takes a bit of time to see what can be taken and from where. EU is now, afaik, making seized Russian assets available to Ukraine, and getting money to buy armament with is quite as important as getting armament. Even more so, because with money you can also buy non-armament supplies, which are also needed.

Finland has never trusted Russia. Sweden tried to, a bit, by generously demilitarising Gotland, up until it had to rearm it a few years back because after there was no military there, suddenly Russian tourists of military serving age started "touring" it. Now there's a permanent base again.

might have a chance to divide both Europe and NATO, and Finland could be such an area to poke.

What are you on about? Do you know how the Winter War and the Continuation War played out? How would Russia attacking Finland "divide" Europe, unless you're implying that Russia is a part of Europe, because we were more discussing in the context of the European Union, not Europe in general. European Union is very strong and there's articles that have been agreed to. International politics don't really work with the "no I'm not gonna, because I don't wonna" attitude.

You're severely underestimating Finland's defenses pre joining NATO. And that (usually American) cockiness is exactly why a lot of people still oppose NATO.
