@ civwarbuff: On what basis do you claim Cuba is "one of the poorest nations" ?
If you're going by GDP per capita, according to World Bank figures, Cuba's GDP per capita in 2013 was $20,649, ranked 58th out of 183 countries, placing it ahead of most other Latin / South American countries, including Venezuela (ranked 62nd), Mexico (67th), Costa Rica (74th), Brazil (75th), Colombia (84th), Peru (89th), and Ecuador (93rd).
