At first I wanted to make some joke about Call of Duty Ghosts, but couldn't come up with anything worthwhile, so let's opt for the serious discussion instead. Don't you guys have UNASUR?
Unasur is a piece of shit, and right now leftist goverments of my country, Mexico, Venezuela and Argentina suck. This hyphotetical alliance would be under other governments, clearly. But that axis Mexico City-Caracas-Lima-Brasilia-Buenos Aires is necessary in order to protect Peruvian interests.
