Security threats loom over this summer's Paris Olympics. France is preparing to prevent terrorist attacks during the Olympic event with a massive police deployment and exhaustive controls.

Macron also warns of Russian interference in the Games. The Olympic Games are a universal spectacle with audiences that can exceed one billion viewers: an appetizing setting for any demand, including the most violent ones. There is precedent: the massacre of Israeli athletes by a Palestinian group in Munich in 1972 opened an era of international terrorism. The moment of greatest risk is the opening ceremony, which for the first time will take place outside a stadium.
