When people talk about 9-11, it is important to clarify exactly "which one"? The first, in 1973, saw the removal of the Chilean government with the help of the USA, and the bringing in of a brutal dictatorship under Pinochet. In 1970, the CIA’s deputy director of plans wrote in a secret memo:

"It is firm and continuing policy that Allende be overthrown by a coup. ... It is imperative that these actions be implemented clandestinely and securely so that the USG [the U.S. government] and American hand be well hidden."

That same year President Nixon ordered the CIA to "make the economy scream" in Chile to "prevent Allende from coming to power or to unseat him." 

Rab Paterson has visited Latin America in 1995, 2012 and in 2016. He reports back what he saw of rising militancy amongst some workers, resisting the increasingly rightwing political & economic situation where pensions are decimated and education is unaffordable, unemployment is rampant and poverty lives side by side with the extreme wealth of the ruling class.
