What would have happened if Augusto Pinochet and other Chilean military officers had launched the September 11th 1973 coup that overthrow Salvador Allende but had relinquished power relatively quickly and allowed (at least mostly) free elections within a few months or at most a year? While I suspect the left would suffer from official or unofficial handicaps in such a situation such as bans on a large number of Socialists and other UP politicians from running for office, even a relatively fair election would have produced a conservative majority. Assume that Allende still kills himself and that the murders and other human rights violations immediately following the coup still occur but taper off by the time of the elections.
