Perhaps the Vatican wants to be culturall sensitive and so is looking for a real "Kazak" to appoint there!
OR the Patriarch of the UGCC (hey, even the Ecumenical Patriarch referred to our Svyatoslav as "Patriarch" recently, didn't he?
speaking of geopolitics . . .) - where was I, ah, yes - our Patriarch could simply appoint such for Kazakhstan.
After all, it is always easier to apologise than to ask for permission . . . things get done much more effectively that way!
