Last September, two graying fighters in the hemisphere’s longest-running armed conflict consented to an awkward handshake. Ernesto Londoño wrote in the New York Times that he watched Juan Manuel Santos and Timoleón Jiménez, alias “Timochenko,” head negotiator for the FARC, shake hands “in stunned silence,” astonished at the diplomatic successes of Colombia’s four years of peace talks. On the evening of October 2nd, international observers reacted once again in stunned silence—this time, however, because the prospects for peace were thwarted by an entirely unexpected outcome. The “Yes” vote lost by less than 1% in a surprise to most observers, who predicted that the referendum would pass.
