Operation Mongoose consisted of a program of covert action, including sabotage, psychological warfare, intelligence collection, and the creation of an internal revolution against the communist government. The U.S. still lacked the capability of effectively getting information to the majority of the Cuban people. They had a trade embargo, denial of bunkering facilities, increased port security, and control procedure on transshipment, technical data, and customs inspection. The U.S. also used diplomatic means to frustrate Cuban trade negotiations in Israel, Jordan, Iran, Greece, and possibly Japan. From the outset, Lansdale and fellow members of the SG-A identified internal support for an anti-Castro movement to be the most important aspect of the operation. American organization and support for anti-Castro forces in Cuba was seen as key, which expanded American involvement from what had mostly been economic and military assistance of rebel forces. Therefore, Lansdale hoped to organize an effort within the operation, led by the CIA, to covertly build support for a popular movement within Cuba. This was a major challenge. It was difficult to identify anti-Castro forces within Cuba and there lacked a groundswell of popular support that Cuban insurgents could tap into. Within the first few months, an internal review of Operation Mongoose cited the CIA's limited capabilities to gather hard intelligence and conduct covert operations in Cuba. By January 1962, the CIA had failed to recruit suitable Cuban operatives that could infiltrate the Castro regime. The CIA and Lansdale estimated that they required 30 Cuban operatives. Lansdale criticized the CIA effort to ramp up their activities to meet Operation Mongoose's expedient timelines. Robert McCone of the CIA complained that Lansdale's timeline was too accelerated and that it would be difficult to achieve the tasks demanded in such a short timeframe.
