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.

These perceived threats prompted Castro to further eliminate "counter-revolutionaries", and to utilize Guevara to drastically increase the speed of land reform. To implement this plan, a new government agency, the National Institute of Agrarian Reform (INRA), was established to administer the new Agrarian Reform law. INRA quickly became the most important governing body in the nation, with Guevara serving as its head in his capacity as minister of industries. Under Guevara's command, INRA established its own 100,000 person militia, used first to help the government seize control of the expropriated land and supervise its distribution, and later to set up cooperative farms. The land confiscated included owned by United States corporations. Months later, as retaliation, US President Dwight D. Eisenhower sharply reduced United States imports of Cuban sugar (Cuba's main cash crop), thus leading Guevara on July 10, 1960, to address over 100,000 workers in front of the Presidential Palace at a rally called to denounce United States "economic aggression". "Time magazine" reporters who met with Guevara around this time described him as "guid(ing) Cuba with icy calculation, vast competence, high intelligence, and a perceptive sense of humor."
