Knowing who carried out an act of terror doesn’t always tell us who was ultimately behind it.
Seeking to explain recent terror attacks in France, conspiracy theorists have resorted to very familiar culprits: the Jews did it, specifically the mystical supermen of Israel’s Mossad. Such a theory is stupid and scurrilous, as well as on so many grounds self-evidently incorrect. That said, the Paris terror spree does raise significant questions about how we assign responsibility for terror attacks and what we can and can’t know by looking at the foot soldiers who carry out the deeds. Nor are debates over false claims and attributions wholly foreign to American history.
