"The study, declassified in 2016… focuses on the role of Clare Boothe Luce as ambassador to Italy, 1953-1957," the release stated. "The author also concludes that the Eisenhower administration, faced with the possibility of civil war in Italy or the Communist Party coming to power legally, was ‘willing to intervene militarily only if the Communists seized power forcibly and then only in concert with other European nations’."
The study was completed in 2012 by Department of Defense historian Ronald Landa.
Landa’s report concluded that US covert aid to Italy continued until the early 1960s.
Because details were lacking in official reports on US foreign relations, Landa said in an author’s note attached to the release that he based his conclusions on CIA records, an examination of Luce’s extensive personal collection at the Library of Congress and records at the National Archives from her tenure as ambassador.
