His argument is not different from mine many years back - Russia considers Ukraine a vital national interest and the west does not, so Russia will go further to prevent Ukraine from turning into a larger version of the Baltic states. Understanding this reality, advocating for Ukraine to fight until victory or death, is in reality advocating for Ukraine to fight until death. This might be advantageous to the collective west (hello Russia's narrative about "fighting to the last Ukrainian") but ultimately isn't actually good for Ukraine. Instead it's likely to produce a worse end result for Ukraine.
