(Leaving out previously established unions/federations like the U.S., E.U., and Russia for the purposes of this poll). [b]African Federation:[/b] While largely underdeveloped now, the African Continent has a lot of potential to be a huge player in the future. Oil, land, gold, diamonds, and economic opportunity will one day reach the continent, and if it works together as one giant entity, it will be incredibly powerful (and that's just economically). [b]Latin American Federation:[/b] While most games like Call of Duty are fiction, the possibility of a Latin American Federation is a very real possibility that has been discussed before. Like Africa, they also have a lot of potential for the future, although they're a bit more advanced than them. [b]Middle Eastern Federation:[/b] Strong, powerful, and the center of attention for the world right now, their oil supplies are only expected to last a few more decades. But don't underestimate how powerful it could be even after it no longer relies on oil exports for money.
