Wow, a United SA. Honestly, that sounds like hell. Can you imagine being in charge of such a thing? Suddenly all those violent, drug-related disputes from every single country are your problem. All those generals who don't get along have to work for you. Poverty, language differences, trade issues, all of it on your table. Ugh. I doubt that South America is headed toward a USA style of collaboration. Maybe something more akin to the E.U, with more soveriegnty and responsibility for each member.
