Watching this with interest. I'm playing a game as Brazil, in Global Crisis I think, although I can't really remember. After having beaten Argentina after their unprovoked attack, and sued for peace as I I was besieging their capital, as my forces were loosing a lot of their momentum, had no hope of conquering it any time soon (was hoping they would declare war again after some time, to allow myself to rebuild, but since that time they decided to become model neighbors and have gone very quiet, even with me sending spy after spy at them to see if I could aggravate them enough into attacking me), and now, have just waited a few years to pass while building up. I've bought pretty much every single tech the other countries have researched, with the exception of nuclear weaponry, have gotten many different and awesome designs, gotten my military production to third in the world, just bellow Russia and the US, and right now, although I'm officially neutral in all present conflicts, I keep supplying the sides I want with units for whatever they can pay (have been selling lots and lots and lots of aircraft to South Korea for their war against Russia, and artillery to Poland and another East European country I forget the name, again for use against Russia).
Good luck with your world, I look forward to see how you play and if how it will develop.
