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.
Legacy of Che Guevara
Despite the formal adulation, Guevara's legacy is less pronounced on a national policy front. In Cuba, Guevara's death precipitated the abandonment of guerrilla warfare as an instrument of foreign policy, ushering in a "rapprochement" with the Soviet Union, and the reformation of the government along Soviet lines. When Cuban troops returned to Africa in the 1970s, it was as part of a large-scale military expedition, and support for insurrection movements in Latin America and the Caribbean became logistical and organizational rather than overt. Cuba also abandoned Guevara's plans for economic diversification and rapid industrialization which had ultimately proved to be impracticable in view of the country's incorporation into the COMECON system. As early as 1965, the Yugoslav communist journal Borba observed the many half-completed or empty factories in Cuba, a legacy of Guevara's short tenure as Minister of Industries, "standing like sad memories of the conflict between pretension and reality".
