The FBI began working with Gaede in a counter-espionage operation intended to penetrate Cuban intelligence using his contacts on the island.
Although from a Peronist background, Gaede joined the Communist Party of Argentina at the age of 21 while serving as a steward of FOETRA, the union of the state-owned telephone company ENTel.
[20] After his application for a Cuban resident visa was turned down, he re-entered the United States in 1977, this time as a tourist.
Still faithful to his socialistic principles, Gaede began to gather technical information from AMD, which he offered to the Cubans in one of his trips to Buenos Aires.
This move enabled Gaede to take material in the trunk of his car and deliver the technology to Cuban agents on the Mexican side of the border.
While under FBI supervision, Gaede obtained a job as a programmer at the Intel chip plant in Chandler, Arizona.
[30] However, before Gaede was fired, he managed to film the entire Pentium process database from his home, ironically, using a terminal provided by Intel.
Shortly after, Gaede fled to South America and began to peddle the technology through the embassies of China and Iran.
[20] Gaede was arrested by Argentine authorities as he attempted to bury tapes and documents, and was subsequently interrogated by the Secretaría de Inteligencia (SIDE) and the CIA in Buenos Aires.
[31] Intel security manager Steve Lund arranged to meet Gaede in Argentina at the Sheraton Hotel on May 14, 1995.
[41] Gaede accuses the Cuban government of masterminding a counter-espionage operation against the U.S. that revolved around Cohen and his commander, Major Onelio Beovides.
[42][43] In 1997, Gaede developed a critique of mathematical physics which was centred upon the semantic issues of the popular presentations of general relativity, quantum mechanics, and string theory.
[44] A documentary titled El Crazy Che was released at the Buenos Aires International Festival on April 17, 2015.
[45][46] This biographical movie narrates Gaede's spying activities in favor of Cuba, Iran and China.
