In 1928, former President Calvin Coolidge visited Cuba. It would be 88 years until the next American presidential trip would take place, if nothing impedes President Barack Obama’s scheduled visit on March 21st. It’s hard to describe the historic nature of Obama’s move towards warmer relations with a country that was so strongly allied with the U.S.S.R. that former President John F. Kennedy and then Soviet leader Nikita Khrushchev came dangerously close to war over the Cuban Missile Crisis. Fast forward to 2014, when President Obama announced his vision to embrace Cuba, whose long-time dictator Fidel Castro had become so ill, he handed power to his brother, Raul. There are signs of change in Cuba, but it is slow. According to human rights activists, there is a disturbing crackdown on political dissidents. Much work remains to improve the lives of ordinary Cubans. For Obama, the effort is worth spending some of his dwindling political capital before he vacates the Oval Office.
