The U.S. blockade on Cuba, imposed for more than 60 years, cost Cuba US$4.2 billion between April 2017 and March 2018, bringing Cuba's total losses due to US sanctions over six decades to US$134.5 billion.
To the Cuban people, the west isn't all populated by viscious megalomaniacs hellbent on destroying other sovereign nations. The ordinary people of the so-called west generally want peace, fairness and justice. What the USA has imposed on Cuba is none of those things. But you only have to look at US history to see what kinds of principles it operates under: throat-cutting, deceit, looting and pillaging, breaking treaties and promises, the mere appearance of democracy, liberty and justice, illegal experiments on its own population, and the systematic ruin of indigenous peoples around the world, from Turtle Island to Diego Garcia to Palestine. The USA's cancer virus program was started in the 1960s with a view to assassinating Fidel. many suspect they succeeded in Hugo Chavez's case.
Decent human beings stand with you Cuba and recognise who the real threat to liberty and justice is in this world.
