France didn’t plan to blow the whistle on the Muslim Brotherhood’s attempt to take over Europe. But that’s exactly what it did a couple of weeks ago, when a classified report from the Ministry of the Interior leaked to the newspaper Le Figaro.

The 73-page document, marked confidentiel-défense, was meant for top officials only.

Based on intelligence files, field investigations, and dozens of interviews, it lays out a stark diagnosis: The Muslim Brotherhood has built an extensive ideological infrastructure in France—not through violence, but through schools, charities, mosques, and soft power. It states: “The Brotherhood’s strategy is to install a form of ideological hegemony by infiltrating civil society under the guise of religious and educational activities.”

The report is the most detailed government study to date of the Brotherhood’s presence in Europe. Written by two civil servants, it draws on months of fieldwork and analysis conducted in France and abroad, with input from diplomats, intelligence officials, academics, and religious figures. Its conclusion is blunt: The Brotherhood operates as a political project. Its goal is not sudden revolution, but gradual transformation. Its targets are hearts and minds. Its strength lies not in secrecy, but in strategic ambiguity. And it is not coming just for France. It is coming for all of the West.
