Jimmy Carter visited Havana, calling for democracy and end to US embargo on Cuba

In 2002, former US president Jimmy Carter went to Cuba. There, he called for an end to the decades-long US economic embargo against the island nation. In the same speech to the nation, in Spanish, Carter told host Fidel Castro it was time to allow for free elections and freedom of speech. More than two decades later, little has changed.
