From the introduction to the interview:

Ernesto Cardenal is not only celebrated in Nicaragua but he is also well-known among Latin America’s intellectual elite and is one of the most widely read poets writing in Spanish today. He is an important spokesperson for the new ideology—a mix of which typifies the unique character of the Nicaraguan revolution—that synthesizes Christianity and Marxism.

Indeed Cardenal is as unique as the revolution he espouses. His greatest influences have been two North Americans—Ezra Pound for his poetics and Thomas Merton for his beliefs. Cardenal has always been deeply interested in North America, in how the American experience is exported abroad. His life, and his poetry, have been very much shaped by the United States involvement in Nicaragua, his country’s struggle for self-determination and the overthrow of Somoza. . . .

They've told me I talk only about politics now.
It's not politics but about Revolution
Which for me is the same thing as the kingdom of God.
