Huh?
You can’t have it both ways—either the Pope does get involved with matters of prudence or he doesn’t. Insofar as he does, sometimes he will do things we agree with and sometimes he will do things that we don’t agree with. On the balance, I think Papal involvement in these sorts of things has been to the good.
One may disagree with the wisdom of the U.S. in normalizing relations with Cuba, but if the U.S. wants to and the Vatican already has, facilitating the desires of the U.S. seems a no-brainer. It is not up to the Vatican to tell the U.S.—”We could help you in the way you want to be helped, but we think that for you it is a bad idea.”
