• The architect and scholar of Paraguayan history Jorge Rubbiani stated: "Alfredo offered all Paraguayans a mirror that since we returned, with disturbing fidelity, the Paraguayan reality of this, and also made it possible to know the facts in their true dimension, demystify, argue about any conflicts that acquired notoriety simply because they never knew the extent of their insignificance.
