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.
Operation Kufire
Operation Kufire was a program that sought to identify and track all communist party members who had flocked to Guatemala during the Arbenz regime. "Via Kufire, the CIA was intent on charting their movements and monitoring or frustrating their machinations." This operation introduced the CIA to Ernesto "Che" Guevara and one member of the CIA team was unsure as to whether it was even necessary to open a file and track Guevara's movements. Ultimately, operation Kufire signified the fear that communism would spread throughout Latin American. Furthermore, it feared a domino effect, whereby if one nation in America were to fall to communism, then it was likely that others would follow. Operation Kufire was intended to safeguard against any further communist uprisings and to track the activities of known communists throughout all America.
