Aquino was in continuous contact with US officials, most probably even intelligence officials while he was at Cambridge. Proof of this is a “Top Secret” National Intelligence Daily dated June 27, 1983 issued by the CIA head, which reported: “Moderate opposition leader Benigno Aquino told senior US officials on Thursday he plans to leave the US and return to Manila in August.” At the time, nobody else knew of Aquino’s plans to return home.
