At the same time that the Buddhist crisis was taking place, a French diplomatic initiative to end the war had been launched. The initiative was known to historians as the "Maneli affair", after Mieczysław Maneli, the Polish Commissioner to the International Control Commission who served as an intermediary between the two Vietnams. In 1963, North Vietnam was suffering its worst drought in a generation. Maneli conveyed messages between Hanoi and Saigon negotiating a declaration of a ceasefire in exchange for South Vietnamese rice being traded for North Vietnamese coal. On 2 September 1963, Maneli met with Nhu at his office in the Gia Long Palace, a meeting that Nhu leaked to the American columnist Joseph Alsop, who revealed it to the world in his "A Matter of Fact" column in the "Washington Post". Nhu's purpose in leaking the meeting was to blackmail the United States with the message that if Kennedy continued to criticize Diem's handling of the Buddhist crisis, Diem would reach an understanding with the Communists. The Kennedy administration reacted with fury at what Alsop had revealed. In a message to Secretary of State Dean Rusk, Roger Hilsman urged that a coup against Diem be encouraged to take place promptly, saying that the mere possibility that Diem might make a deal with the Communists meant that he had to go.
