Colombian President Juan Manuel Santos is receiving the Nobel Peace Prize in Oslo today, in recognition of his four-year effort to guide peace negotiations with Colombia’s largest rebel group, the FARC. The October announcement about the prize came just days after Colombians rejected a referendum on the historic peace agreement to end the armed conflict that has plagued the country for half a century. In late November, the two sides pushed through a revised peace deal addressing some of the concerns of those who voted against the referendum. Santos avoided another referendum by getting the senate and the lower house to approve the new pact. The outcomes of referendums — whether in Colombia, or the June Brexit vote or December’s Italian referendum — make it clear that getting people to vote for government initiatives is harder than one would expect.
