Don't be so condescending - Finland is one of the few countries that successfully resisted a Russian invasion. It is very much capable of protecting itself, much more so than Ukraine (which is also doing it, albeit with significant support from the west).
The NATO (and the US actually) benefits a lot by Finland joining, and will benefit from Sweden joining too - only a matter of time.
Dunno man. Booting the invaders and keeping sovereignty after your tiny nation of 3 million is invaded by an army of over 500K soldiers seems like a win to me, especially when literally every other neighbor fell. But whatever. Finland's ready for Russia.
