Now that he has seen what has happened to the Knights he ought to be very, very careful what he commits to, with this Pope. The Knights have the diplomatic status of a sovereign state and the Vatican City State has technically invaded it. What chance would the SSPX have if the Pope got his hands on it and its property?
I wonder what the UN and the international community would do if one day Italy were to decide to take over Vatican City now that the latter has set a precedent.
