The conflict in the Middle East has always had an impact on the world, producing polarizations everywhere. The reportage recounts the consequences in France, the country that is home to the largest Muslim and Jewish communities in Europe. Here, since October 7, pro-Israel or pro-Palestine demonstrations have flooded the squares. And expressions of solidarity have often been replaced by acts of discrimination and violence. On the one hand, protests against Israel's war and anti-Zionism have merged with anti-Semitism. On the other, it has become increasingly difficult to criticize Israeli bombings without being accused of racial hatred, with many Muslim supporters of Palestine becoming victims of Islamophobic attacks by the authorities. The reportage investigates how the explosion of the Israeli-Palestinian conflict has exposed internal tensions in French society, producing a historical, political and cultural clash, with sometimes paradoxical features. On one side, with a radical left that makes the Palestinian question an ideological battle to the point of risking slipping into ancient prejudices. On the other, a far right, heir to xenophobic ideology, which today stands up in defense of the Jewish community.
