We are told by the Catholic News Agency that Msgr. Georg Ratzinger, brother of the Pope, recently gave an interview to the Italian journalist Andrea Tornielli. In this interview - according to the article - Msgr. Ratzinger "revealed several unknown details from the childhood of the Pontiff, such as when he said one time that Benedict would be a good name for a pope, and that he never attended Hitler Youth meetings he was obliged to sign up for."
Apparently the author of the article has not read then Joseph Cardinal Ratzinger's Milestones, in which he very clearly states that he never attended meetings of the Hitler Youth. Unkown details, indeed.
