Why would Czech Republic, formerly a province of Austria-Hungary, need to become "westernized"? It was "westernized" centuries ago -- at the time of the first Přemyslids, in fact, when the Eastern church, courtesy of Cyril and Methodius, was replaced in Bohemia for political reasons by allegiance to the (Catholic) Regensburg diocese.
