Russia Ukraine war, page-36653

you're suggesting as a precedent for Donbas going to Russia, I presume , as a deal to end the war .
Do take your point and has some merit except there are a few differences between the Finnish situation and the Ukranian one .

1.This isn't the first "bite" by Russia , Crimea already gone !
2. Finns as far as I know didn't get the support internationally that Ukraine is getting .
3.Zelensky has said Nyet to Russia about ceding territory .

Th similarity is that the Finns and Ukranians rather spirited determined people and both invaded without cause .
The other thing to bear in mind more broadly is rewarding an invader with land for doing it sets a bad precedent - as Crimea did !
Effectively kicks the can down the road inviting the next foray ...as crimea did and which is why Europe are so supportive of Ukraine .
Some countries see themselves as potentially next in the line .
