I just went back compared some numbers now that we know what the minimums economic power is, and what they may be able get to with a realistic pod. An achievable economic milestone may be beating the Argentinian economy and becoming the 2ed largest South American economy and in the worlds top 25 economys. In order to do this they would only need a 25% increase of there current GDP which makes this achivable as part of our work will be done with little to no work as a unions seem to be naturally beneficial for the the joined parts then that would separately because of open trade and a free flow of people (kind of like the EU) but also perhaps a larger peru/bolivion union would be intimidating enough to stop otl wars that occered in bolivia from even starting such as the choco war which may happen naturally as previously started or if using a pod they could join the war of the triple alliance and with how bad Paraguay lost any more damage and they might just cease to be a country and be divided by the now Quadrupal alliance (some estimated over 70% of there population died in otl's war). And all of this is even before we have suggested economic pod's which should smooth out the road to the 25% growth we want.
