From the horse's mouth
First in a (hopefully) regular series.
Here is Fidel Castro, speaking in 1965 about why the Cuban media would never publish or broadcast "positive" news from capitalist countries:
"True, everything that we say about the United States here [in Cuba] refers essentially to the worst aspects of the United States, and it is very rare that things in any way favorable to the United States will be published here … We always try to create the worst opinion of everything in the United States, as a response to what they have always done with us. We emphasize the worst things. We omit things that could be viewed as positive."
