About l'affaire Dadak, concerning the activities of a Franco-Polish arm dealer Pierre Dadak, Feinstein stated: "Dadak's story reflects the complete amoral nature of the arms trade. The distinction between arms dealers and grifters is extremely fuzzy. A lot of these people are almost caricatures, they have huge personalities, they’re delusional. The extraordinary thing is how company after company, government after government, actually fall for these people. And the reason they do it is because everything that happens in this trade is secret, so it provides absolutely fertile ground for these sorts of conmen".
