HAVANA (AP) — Fidel Castro responded Monday to President Barack Obama's historic trip to Cuba with a long, bristling letter recounting the history of U.S. aggression against Cuba, writing that "we don't need the empire to give us any presents."

The 1,500-word letter in state media titled "Brother Obama" was Castro's first response to the president's three-day visit last week, in which the American president said he had come to bury the two countries' history of Cold War hostility. Obama did not meet with the 89-year-old Fidel Castro on the trip but met several times with his 84-year-old brother Raul Castro, the current Cuban president.

Obama's visit was intended to build irreversible momentum behind his opening with Cuba and to convince the Cuban people and the Cuban government that a half-century of U.S. attempts to overthrow the Communist government had ended, allowing Cuban to reform its economy and political system without the threat of U.S. interference.

Fidel Castro writes of Obama: "My modest suggestion is that he reflects and doesn't try to develop theories about Cuban politics."

Castro, who led Cuba for decades before handing power to his brother in 2008, was legendary for his hours-long, all-encompassing speeches. His letter reflects that style, presenting a sharp contrast with Obama's tightly focused speech in Havana. Castro's letter opens with descriptions of environmental abuse under the Spaniards and reviews the historical roles of Cuban independence heroes Jose Marti, Antonio Maceo and Maximo Gomez.

Castro then goes over crucial sections of Obama's speech line by line, engaging in an ex-post-facto dialogue with the American president with pointed critiques of perceived slights and insults, including Obama's failure to give credit to indigenous Cubans and Castro's prohibition of racial segregation after coming to power in 1959.

Quoting Obama's declaration that "it is time, now, for us to leave the past behind," the man who shaped Cuba during the second half of the 20th century writes that "I imagine that any one of us ran the risk of having a heart attack on hearing these words from the President of the United States."

Castro then returns to a review of a half-century of U.S. aggression against Cuba. Those events include the decades-long U.S. trade embargo against the island; the 1961 Bay of Pigs attack and the 1976 bombing of a Cuban airliner backed by exiles who took refuge in the U.S.

He ends with a dig at the Obama administration's drive to increase business ties with Cuba. The Obama administration says re-establishing economic ties with the U.S. will be a boon for Cuba, whose centrally planned economy has struggled to escape from over-dependence on imports and a chronic shortage of hard currency.

The focus on U.S-Cuba business ties appears to have particularly rankled Castro, who nationalized U.S. companies after coming to power in 1959 and establishing the communist system into which his brother is now introducing gradual market-based reforms.

"No one should pretend that the people of this noble and selfless country will renounce its glory and its rights," Fidel Castro wrote. "We are capable of producing the food and material wealth that we need with with work and intelligence of our people."
