Dear Salvatore, thanks to Socrates, I have your favorite phrase to leave your opinion as written, because “I only know that I know nothing.” Imagine that now you question the US federalism with more than 200 years of history and that of Switzerland that also has history since its founding in 1848. In addition, Spinelli in his statement of Ventone and later in the days he worked in the institutions of the EU has made it very clear what is federalism. The federalist groups that emerged in the 1940s and 1950s wanted a federal Europe after Schumann’s declaration in 1950 all the illusion of the federalists fell deeply and has not yet risen head again. The federalist groups of the 1960s and later have only the name of federalists, but they either have no idea what federalism is. I mean, they call federalists, but they're not. Many of these “federalists” are only waiting for a position in the Institutes. EU
