"He [Allende] embarked on what he called "the Chilean path to
socialism," nationalizing the copper industry that had been dominated by U.S.
companies and using the money to fund land redistribution while improving health
care, education and literacy. The embrace of socialism, which included a
three-week visit by Cuban leader Fidel Castro, was a Cold War nightmare for U.S.
President Richard Nixon, who approved a covert campaign to aggravate the
country's economic chaos and helped provoke the military takeover." (thanks Amir)
