The U.N.'s authority here is ... what?
None. The UN has no jurisdiction over the Vatican or any other sovereign nation.
The UN is an organization that counts, as Marco Rubio just said in an editorial, "serial abusers and murderers of men, women, and children as members of its Commission on Human Rights. It has been unable to slow North Korea and Iran’s march toward nuclear weapons. It has proven feckless in its ability to prevent atrocities in places like Syria. It has routinely given a platform for state sponsors of terrorism to successfully condemn Israel. Its own “peacekeepers” have committed crimes against women around the world."
Clean up your own house, you perfumed princes. You're a running joke.............
