In case he hasn't been said;
Jorge Eliecer Gaitan, he was probably one of the worst missed oportunities, if not the worst, not only in Colombian history but in Latin american history, he was a left leaning politician who was somehow, liked by the CIA, who in a report said that he was of no threat to the US and even actually asked for the go ahead to support him, his policies would ahve changed Colombia for the better and without the violence and chaos that followed his death Colombia could reasonably be very close if not a first world country with his policies, also his survival and influence abroad might have meant that more people like him, left leaning people who despite that disliked the USSR and wanted to keep the US as an ally, might be more prevalent in Latin America.
