“Revolutions are not made at the whim of men; nobody could say that the whim of a group of men could lead people towards a revolution.  Revolutions are made by necessities and people are not guilty for why revolutions happen; the people make revolutions forced by necessities, even though those of us involved in making them do so with great pleasure”.

"In Cuba we have never cultivated hatred against the American people or blamed them for the aggressions perpetrated by the governments of that country. That would have run contrary to our political doctrines and our internationalist conscience, both well-proven throughout many years, and increasingly rooted in our ideas."

“Cuba is increasingly becoming a country with not only great intellectual and artistic talents but also with many educators, scientists and hundreds of thousands of people capable of producing wealth with their learned minds. This is but a proof of what can be done despite the inherited underdevelopment and the longest economic and financial blockade that any people has ever endured! ”
