In politics, there’s nothing new in a group radically changing its way of seeing and acting once it has become a big organisation, a mass party. One could cite several examples of such metamorphoses. One could to some extent apply it to the Bolshevik party after the revolution. But what’s striking about the International Communist Party of Italy is the surprising rapidity with which its main leaders have undergone such a change. And this is all the more surprising in that the Italian Party, both numerically and functionally, is in essence an enlarged fraction.
