I mean, I don't blame Zelenskyyyyyy for trying to get what he can. That's kind of his job. And he is in a tough spot. Nobody would like part of their country taken by a foreign power.
But that doesn't mean we just give him everything he wants with barely a check on it. We can't fight every war in the world. Even if it sounds good in principle, it isn't feasible. We simply can't be the world's policemen in every matter.
And to be honest, I think an exchange like that should happen behind closed doors. I think that guy is pretty crooked but I'm not sure it's necessary to humiliate him in public like that.
