Sure, there wasn't any official attribution, but the US aren't the only player in town either.
EDIT: As an aside, an ex-director of the DGSE[1] (french CIA basically) complained that there tend to be a general misunderstanding between the communication modes of western countries and middle-east countries, the former prefers to proverbially "Speak softly and carry a big stick" while the latter prefer a good incendiary speech as a form of catharsis. As a result western audiences tend to take some speeches too literally, as if they were a plan of action while the discourse wasn't made with them in mind.
