What Will Happen in Colombia after Peace with Las FARC?

Since November peace negotiations between President Santos' administration and the FARC have begun in Cuba, much to the regret of hardliner and former president Álvaro Uribe Velez and the Uribistas. Thanks to the Norwegian government who has made considerable efforts in silent diplomacy to bring the two parties to the negotiation table, define the agenda and the road-map. Meanwhile in Colombia, Uribe continues to criticize the peace process, stating that you don't negotiate with terrorists and that the current administration shows more interest in dialogue with "terrorism" than National security. After a period of ignoring Uribe, Juan Manuel Santos has started a first offense to silence Uribe and his followers by stating Uribe sought peace talks with the FARC himself for five years during his two terms.
What would be the chance for the peace process to succeed? What are the consequences of peace? Will there be an all-encompassing peace in Colombia when the FARC will give up its arms? What are the consequences of failure? Interesting questions...
