According to the 1952 documents, it was Christopher Steel, the No 2 official in the British embassy in Washington, who "pitched" the idea of the coup to US officials amid the US-Britain talks which had begun in October. The document also says that the British officials rejected Paul Nitze's suggestion that, instead of executing a coup, they mount a "campaign" against Ayatollah Abolqasem Kashani, "a leading opponent of British involvement in Iran's oil industry", and the communist Tudeh Party. They "pressed US for a decision" since they knew "the Truman administration was in its final weeks". According to Wilber, the British Secret Intelligence Service worked with CIA to form a propaganda campaign via "the press, handbills and the Tehran clergy" to "weaken the Mossadeq government in any way possible".
