"I suppose all of us were at risk of a heart attack upon hearing these words from the President of the United States."
Fidel has responded to President Obama's visit. The above irony refers to Obama's speech to the Cubans in which he talks about a new era of cooperation and unity even as the Cold War era blockade remains in place.
Fidel's long article released today validates the assumptions of many Cuba watchers, that if the US thinks it can recolonize Cuba by stealth with McDonald's restaurants and Wal Marts it has another thing coming, that the Cuban Revolution is simply too deep, Cubans are too smart, and they just won't allow it. They know what they have.
One the ways the Revolution is part of every Cuban is talked about in a book I'm reading by Rebecca Gordon-Nesbitt, "To Defend the Revolution is to Defend Culture," in which she traces how the artistic and cultural and educational development of every Cuban citizen was made a conscious part of the revolution from the very beginning. In other words, the exact opposite of the United States, where we can't even bear the thought of of a poor child eating let alone being educated, or becoming an artist as every Cuban does.
Cubans have long been observing how their relatively uneducated American neighbors are led around by the nose by politicians, Republican and Democrat, and now by people like Donald Trump, and may well have thought Obama's words probably sounded pretty nice to the average American listening back home.
