According to the British doctrine, worked out by Churchill already in the final phase of the Second World War and formalised straight away after that, there were three things that Italy could absolutely not do. The first: have or construct a political system that was thoroughly democratic, that is the alternation of a Majority and an Opposition in government, because of the presence of a Communist Party that was the strongest in the Western world; the second was to think autonomously about security policy; and the third thing, the most important thing that Italy could not do, according to Churchill’s doctrine, was to have an autonomous foreign policy based on Italy’s own interests.
