Perhaps Helms's most controversial undertaking as CIA chief concerned the subversive efforts to block the socialist programs of Salvador Allende of Chile, actions done at President Nixon's behest. The operation was code-named Project Fubelt. After Allende's victory in the 1970 election, CIA jumped into action with a series of sharp and divisive maneuvers. Nonetheless, Allende was inaugurated as president of Chile. Thereafter, the CIA's efforts markedly declined in intensity, though softer tactics continued. Three years later (11 Sept. 1973) the military coup led by Augusto Pinochet violently ended the democratically elected regime of President Allende.
