Yeah that's how wars usually end, right? A country leaves and then negotiations start.

Since we're in imaginationland, how about all ukrainians get a free dolphin?

And if Ukraine can't win militarily (which they clearly can't), how does that happen?

Your comment makes me want to see a fan cut of Captain America where he just gets the shit beaten out of him and his limbs ripped off and he dies and every five minutes "I can do this all day" but it never turns around and he fucking dies. He never appears to make a come back. He just keeps getting his ass kicked and never stops saying the line. Except it's not his ass getting kicked, it's some random children he took off the street and forced to be child soldiers or he'd kill them. And he just keeps saying "I can do this all day" while tens of thousands of people keep getting killed and not once for any reason or goal that progress is made towards. Just tens of thousands of dead bodies every month. "I can do this all day" except he's not even there he's on an internet forum. It's still tens of thousand of dead bodies but not his. And he'll never give up. But he'll never get any closer to winning. Just death to countless people who aren't him. He can do it all day. And every time he says it you can tell he feels really cool and badass. He's Captain America. He doesn't quit just because it looks bad.

Do you think it is realistic that Russia will unilaterally pull out? The war will end when Russia leaves, but Russia isn't going to leave until they are pushed out, negotiations are had, or Ukraine is destroyed. The first possibility is becoming increasingly more unlikely, and the last is something that nobody should want

That leaves negotiations. I think Ukraine should come to the table while they still have some leverage, which is decreasing every week that they throw their men into the meat grinder without meaningful gains.
