Yeah, he's old and didn't use the happiest words.. but the Vatican clarified he didn't mean "unconditional surrender" and instead only meant "negotiate a peace deal".

AFAIU (and also AFAIC - "as far as I care") It's not entirely clear yet if the Pope suggests that Ukraine should give up territory in exchange for peace (and what about reparations?) or if he just means "be good people and make peace" (which would be much more in line with how he usually talks). I don't think whatever the Pope thinks will really be of much consequence given how geopolitically relevant this war is ("The Pope? How many divisions has he got?")

This whole news/argument serves as great marketing for the TV program where the the interview will be broadcasted (which I'd assume is not unintentional)
