In 1982, the United States removed Iraq from its list of nations that sponsor terrorism and tacked on Cuba.
Times, as they say, have changed.
The U.S. is pulling Cuba from the list after more than 30 years, leaving only Sudan, Syria and Iran. Many believe the move is long overdue and that the reasons it hadn't happened already are more about politics than terrorism.
But 33 years ago, that wasn't necessarily the case.
The U.S. had accused Cuba of supporting Colombia's largest group of rebels, known as the Revolutionary Armed Forces of Colombia (or FARC), which is on America's list of terrorist groups. The U.S. government believes it uses bombings, kidnappings and hijackings as well as traditional warfare in attempts to overthrow Colombia's government.
Founded in 1964 with a goal of turning Colombia into a Marxist nation, FARC was modeled after Castro's successful revolution in Cuba years earlier. Various rebel groups have now battled with the Colombian government for more than 50 years, resulting in nearly 220,000 deaths.
The American government also said Cuba was housing separatists from Spain who were part of a group called Basque Fatherland and Liberty (known as ETA). The group -- also labeled a terrorist organization by the U.S. -- called for a Basque nation and was known for assassinating political officials.
The U.S. bolstered its case against Cuba as recently as 2013, when the American government placed a woman named Assata Shakur on the FBI's list of 10 most wanted terrorists. Shakur fled to Cuba after escaping jail in 1979. She was locked up after she was convicted in the murder of a police officer. She was a member of the Black Liberation Army, a group known for attacking police before it dissolved in the 1980s.
But recent State Department reports reveal there's no evidence showing Cuba provides support to any terrorist groups. By keeping Cuba on the list, though, the U.S. was able to justify an economic embargo against the country and ward off other nations from doing business with them.
Cuba has recently hosted peace talks between Colombian rebels and the Colombian government, and many Basque nationalists have been sent home to Spain.
Cuba's designation had been a thorn in otherwise warming relations with America. Without it, the U.S. and Cuba move closer to reopening embassies with each other.
