Guillen really has a thing for the Soviet Union

It seems to me that Guillen, an Africuban, wants his country, Cuba, to be more like the Soviet Union.  He notices that there is absolutely no Soviet influence in Cuba.  "Never have I seen a Soviet trust in my country...a bananna plantation."  I get the feeling from this poem, that Guillen actually admires the Soviet Union.  Being part African, Guillen most likely experienced a fair amount of racism.  He claims that in the Soviet Union, he"never saw White Only-Colored Only" signs that he was probably so accustomed to seeing. He points out the Cuban corruption and the trust of Soviets when he talks about the different ships being questioned.  Those ships never "sent a thing without the gentle taste of friendly bread and generous flavor of a brother's voice."  Guillen sees the communist Soviet Union as a brother, unlike much of the world at that time.  At the end of the poem, Guillen talks about joining up with the Soviet Union to fight.  He knows that he is offering to the Soviets a dark and candid heart," but he believes very strongly in the Soviet Union's overall strength and ideals.
