In 1932 Emil Ludwig interviewed over several days Benito Mussolini and then published with Mondadori publishing house the result, as the book Talks with Mussolini. After having approved the draft with only minimal corrections, Mussolini blocked the book and imposed more extended modifications. Nowadays the complete version is available (in Italian, since 1950).
My question is: are the talks as reported by Ludwig reliable? In other words, may we take the sentences attributed to Mussolini as his own?
