There is no hard evidence of direct U.S. assistance to the coup, despite frequent allegations of such aid. Rather the United States - by its previous actions during Track II, its existing general posture of opposition to Allende, and the nature of its contacts with the Chilean military- probably gave the impression that it would not look with disfavor on a military coup. And U.S. officials in the years before 1973 may not always have succeeded in walking the thin line between monitoring indigenous coup plotting and actually stimulating it.
