Newly declassified documents from the Trump administration reveal details of CIA operations aimed at containing the communist threat in Italy. The CIA supported Pietro Nenni's Socialist Party (PSI) to counter the Italian Communist Party (PCI).
In April 1963, CIA officials informed the Kennedy administration about supporting Nenni's “autonomists.” This involved providing financial aid to bolster the PSI ahead of the 1963 Italian elections. The operation was deemed successful, with funds reportedly delivered in April 1963.
The 1963 Italian election saw a victory for the Christian Democrats, but the PSI increased its seats. Despite initial setbacks in forming a coalition government, the US continued to urge Nenni to collaborate with the Christian Democrats to weaken the communists.
The CIA viewed this outcome positively, with a government composed of pro-US and pro-NATO figures and notably, without communists.
