NATO supporting Ukraine in their defensive war is horrific in your opinion, but Putin sending hundreds of thousands of young Russian men to die isn't? Your moral compass sounds deeply flawed.

Perhaps Ukraine should have agreed to never join NATO, but I'm not sure whether this would have prevented the war. After all, Putin seems to genuinely think Ukrainians are not real ethnicity, and that the land thus belongs to Russia. From a Finnish point of view, Russians have again and again proved they cannot be trusted. Even during the good period between collapse of the Soviet Union and invasion of Crimea, Russian air force regularly violated our airspace. Intelligence operatives kept buying property that made no financial sense, but was located near military installations or critical infrastructure. Why would a friendly nation do this?

I believe in negotiations and diplomacy with Russia, but ONLY when all that is backed by enough military force. Because that is what Russians ultimately respect. The Soviet Union annexed or enslaved its weaker neighbors into puppet states, and that is what Russia ultimately aims to do. Ukraine is only the first step.
