Many of these leaders that are pushing for the Prosur initiative criticized UNASUR for being a politicized institution that responded to the interests of left-wing leaders such as Hugo Chavez or Lula in Brazil […] I think they are doing the exact same thing with Prosur. How would this institution survive after the incumbents leave office? That is the key question. If we are going to create new institutions every time there is a political shift in Latin America then we are not going to build real sustainable integration.
