Without going into the details of how and why any specific person came to have a specific belief, I have the following heuristic: when someone makes a claim, especially when the stakes are high, I ask "who does that benefit?" Now that doesn't mean that they're intentionally trying to benefit whomever that benefits. It doesn't mean that they're wrong.
So, Russia invaded and occupied Ukraine. Who does it benefit to be claiming "there should be peace?"
Obviously it benefits the invader.
It's easy to have peace, you just have to surrender.
Another heuristic that I have is to ask: "do this person's claims always benefit the same side?"
Ukraine is a broken country and the more this war goes on the worse it's going to get. So I'd say it certainly benefits a lot of Ukrainian men who are destined for an early grave "that there should be peace".
Every realist out there can see that -absent WW3- Ukraine will lose this war, the only question being the scale of destruction and the number of the dead.
