I'm out of my depth to even imagine what exactly is the beef that would lead to something like this, but it's probably some kind of geopolitical tit-for-tat bullshit.
Maybe some shit related to Israel vs. France's interests in Lebanon.
France has a million little pressure-points with which to respond. Perhaps they might put an op-ed in Le Figaro declaring circumcision is barbaric and should be banned...
Whatever is their best move, they certainly know it, and they're certainly taking appropriate action. Geopolitics is, after all, their forte.
It was some kind of geopolitical / international mafia bullshit. I'm calling it.
It's probably not possible to track down whoever did it, but the state can make it more difficult for everyone who is international mafia adjacent...
