Americans have long been fascinated by Cuba. A mere 90 miles divide the two countries, and their histories have been entangled since the turn of the last century, when the U.S. occupied Cuba after the Spanish-American war. The countries’ relations only grew more complicated from there. Fidel Castro assumed power in 1959, building a one-party Communist state that controlled land, the economy, and the media. He leaned toward the Soviet Union, spurring everything from near-catastrophic confrontations to comical assassination attempts. Several surges of refugees landed on Florida’s shores, building a vocal presence and political opposition to Castro within the United States. And successive American presidents maintained strict economic and travel sanctions and couldn’t budge the stalemated diplomatic process. Barack Obama has made few concrete changes, despite proclaiming the Cuba policy a "failed” one. What do Americans need to know about Cuba, and what’s next for Cuba and the U.S.? Julia Sweig, author of Cuba: What Everyone Needs to Know and a senior fellow and director for Latin America studies at the Council on Foreign Relations, visits Zócalo to explain the history of Cuba, its difficult relations with the U.S., and where both countries should go from here.
