passage: Che Guevara
Guevara was reluctant to return to Cuba, because Castro had made public Guevara's "farewell letter"—a letter intended to only be revealed in the case of his death—wherein he severed all ties in order to devote himself to revolution throughout the world. As a result, Guevara spent the next six months living clandestinely at the Cuban embassy in Dar es Salaam and later at a safehouse in Prague. While in Europe, Guevara made a secret visit to former Argentine president Juan Perón who lived in exile in Francoist Spain. There Perón warned Guevara that his plans were suicidal. Later, Perón remarked that Guevara was "an immature utopian–but one of us–I am happy for it to be so because he is giving the yankees a real headache."
