text: For the Ustasha, “relations with the Vatican were as important as relations with Germany because Vatican recognition was the key to widespread Croat support.” (Phayer, The Catholic Church and the Holocaust, 1930–1965 (2000) p. 32) “It is well known that many Catholic clerics participated directly or indirectly in the Ustaša campaigns of violence.” (pp. 34-35) Pope Pius XII could not plead ignorance to these atrocities. “Both the nuncio and the head of the [Croatian] Church, Bishop Alojzje Stepinac, were in continuous contact with the Holy See while the genocide was being committed." (p. 30) So, yes, the Vatican has a moral obligation to these Holocaust victims regardless of court decisions. 
  There is not going to be legislation in regards to Alperin v. Vatican Bank. The case was decided re: under what conditions US courts have jurisdiction in another sovereign state.
