Fidel Castro holds up a photo on June 10, 1962, which he claims shows a USA spy plane on a photo reconnaissance mission over the Soviet freighter ten miles off the northern coast of Cuba.

In a blistering commentary following Obama's historic visit, the former dictator let fly in an open letter riddled with sarcasm, basically telling the President of the United States not to let the door hit him on the way out. Castro said Obama's comments were alien and foreign to Cubans when Obama said, "Cuba, like the United States, was founded by slaves brought from Africa; like the United States, the Cuban people have inheritance in slaves and slaveholders".

Demonstrating he isn't quite ready to move on, Castro also wrote the Bay of Pigs invasion by the Kennedy administration as a "mercenary force with cannons and armored infantry, equipped with aircraft ... trained and accompanied by warships and aircraft carriers in the USA raiding our country".

In his first published remarks about the visit, Mr Castro seemed unwilling to forgive and forget more than a half-century of enmity between the two countries, declaring in the Granma newspaper: "Listening to the words of the USA president could give anyone a heart attack".

The 1,500-word letter titled "Brother Obama" is laced with anecdotes from five decades of rocky bilateral relations that Mr. Castro suggests ought to make islanders skeptical of Washington's olive branch.

Mr Castro implies in the column that he was disappointed by Mr Obama after initially having high hopes for the USA president.

Many have wondered how Fidel Castro has been reacting to the rapid changes that have taken place in Cuba since he stepped down due to an illness in 2008.

"For Cuba, the danger is that the US will attempt to swallow it up", said Narine. The government led by the Castro brothers has a long history of human rights violations to the point that Cubans have fled to America for generations.

"Voters should be able to choose their governments in free and democratic elections", he said in a speech carried live on Cuba's tightly controlled state television. "Obama gave a speech in which he used the most syrupy words", Fidel wrote.

Both leaders have committed to continuing to normalise relations between the two nations after reopening diplomatic ties in December 2014. "Nobody should be under the illusion that the people of this dignified and selfless country will renounce the glory, the rights or the spiritual wealth they have gained with the development of education, science and culture".
