“Our Revolution has four things and they precisely constitute reasons to be admired by the Cubans: this is, in the first place, a revolution that has people; it is a revolution where the government of the republic can say that it has an army; it is a revolution that makes laws that are truly revolutionary.”
“I have always lived, and I will continue to live quietly, because I know how to defend the rights of my people with dignity, as well as the honor of the small, poor and weak nations, and I have always been moved by a profound sense of justice. I am a revolutionary and I will die being one.”
“While violence and war spread and reign in the world, Cuba and its people will rise up as defenders and symbols of the most human and genuine principles that must and can reign on this Earth.”
