Che Guevara
In Guevara's private writings from this time (since released), he displays his growing criticism of the Soviet political economy, believing that the Soviets had "forgotten Marx". This led Guevara to denounce a range of Soviet practices including what he saw as their attempt to "air-brush the inherent violence of class struggle integral to the transition from capitalism to socialism", their "dangerous" policy of peaceful co-existence with the United States, their failure to push for a "change in consciousness" towards the idea of work, and their attempt to "liberalize" the socialist economy. Guevara wanted the complete elimination of money, interest, commodity production, the market economy, and "mercantile relationships": all conditions that the Soviets argued would only disappear when world communism was achieved. Disagreeing with this incrementalist approach, Guevara criticized the "Soviet Manual of Political Economy", correctly predicting that if USSR did not abolish the law of value (as Guevara desired), it would eventually return to capitalism.
Che Guevara
In August 1961, during an economic conference of the Organization of American States in Punta del Este, Uruguay, Che Guevara sent a note of "gratitude" to United States President John F. Kennedy through Richard N. Goodwin, Deputy Assistant Secretary of State for Inter-American Affairs. It read "Thanks for Playa Girón (Bay of Pigs). Before the invasion, the revolution was shaky. Now it's stronger than ever." In response to United States Treasury Secretary Douglas Dillon presenting the Alliance for Progress for ratification by the meeting, Guevara antagonistically attacked the United States claim of being a "democracy", stating that such a system was not compatible with "financial oligarchy, discrimination against blacks, and outrages by the Ku Klux Klan". Guevara continued, speaking out against the "persecution" that in his view "drove scientists like Oppenheimer from their posts, deprived the world for years of the marvelous voice of Paul Robeson, and sent the Rosenbergs to their deaths against the protests of a shocked world." Guevara ended his remarks by insinuating that the United States was not interested in real reforms, sardonically quipping that "U.S. experts never talk about agrarian reform; they prefer a safe subject, like a better water supply. In short, they seem to prepare the revolution of the toilets." Nevertheless, Goodwin stated in his memo to President Kennedy following the meeting that Guevara viewed him as someone of the "newer generation" and that Guevara, whom Goodwin alleged sent a message to him the day after the meeting through one of the meeting's Argentine participants whom he described as "Darretta," also viewed the conversation which the two had as "quite profitable."
