Your assuming that he isn't Russian. Russia seems totally willing to sacrifice as many lives to Putin as Putin wants.

What's really pathetic about these call for Ukraine to give up is that Russia still wouldn't win. For a so-called superpower, the clash of armies should have been an easy win. The actual hard part is the occupation. Zelinski could sign the whole country over to Putin today, and it would just guarantee that the bloodshed continues for years or decades. Even in areas that leaned towards Russia, Ukrainians are of no mind to simply surrender.
