You’re talking to a Finn whose grandparents on both sides lost their homes to stalinist USSR. A sapling of a plant they brought with them grows in my yard. I’ve visited the locations and met the new inhabitants (normal people). Trust me, I know land loss sucks. War also sucks, and much as I hate realpolitik… sometimes there’s realpolitik. Of course in the end it’s up to the Ukrainians how long and for what they are willing to fight, with access to whatever aid (hopefully more) they have.
