The post-concert controversy this year concerns the physicist Carlo Rovelli and the public spat with the Minister of Defense Crosetto. Rovelli yesterday unearthed a heartfelt pacifist intervention, but he aimed straight. He attacked military spending and the "instrumental of war peddlers" who build instruments of death "to kill each other."

"International tension has never been as high as it is now," he said. And then the direct blow to a target that lacked the name and surname, but well centered in the crosshairs: "In Italy, the Minister of Defense was very close to one of the largest arms factories in the world, Leonardo". Buffy.

Crosetto, who said he had not listened to the speech live because he was traveling to Baghdad, responded by turning the other cheek via social media, inviting Rovelli to lunch to explain how he has always worked for peace. And then in La Repubblica instead of that cheek he preferred to launch the counteroffensive: "I am not a pacifist, but I am a minister. He's physical."

"I greatly appreciate the courtesy of the Minister of Defense, and his kind invitation to dinner, and I thank him. But the question I raised in my speech on May Day is not personal between him and me. It's politics, it's about the future of all of us, and I would like it to be discussed in the country, not at dinner for two." This is how Carlo Rovelli responds on Facebook to Defense Minister Guido Crosetto.

Everything suggests that the clarification between the two will not be there, not only because lunch has been confused with dinner, but above all because in general this edition of the Concertone was not liked very much by the Government. Culture Minister Gennaro Sangiuliano told reporters in Agrigento that "not a beautiful page has been written on that stage". The May Day stage confirms its traditional vocation of struggle and controversy. Before, during and after.
