This is a really cool concept for a scenario- it seems like people have been talking about making a modern world scenario for ages, but you've finally done it! You deserve a lot of kudos for that.
That said, it seems to me that this scenario has a ton of potential but needs a lot of work to get there. The US has way too many cities, too close to each other; it's a problem that doesn't seem to be replicated in any other part of the world. Most civilizations appear to have only marines as units, which is pretty inaccurate. Many elements of the scenario appear to be left over from Genghis Kai's 1940 AD scenario, including the year, leader names, flags, civics, etc; also the civs are inexplicably named "American tribe," "Belgian tribe" and so forth.
A few more strategic suggestions- what about including longstanding alliances like NATO in the form of defensive pacts, and putting western forces in Afghanistan as in reality? And maybe small one-city civs, like Guatemala, could replace the major areas of minor nations, like Indonesia, Pakistan or the DR Congo. Modern international relations could be modeled better, too; the current relations between civs seem a little random (the US is on fine terms with Iran and Cuba, for example, but is annoyed with Britain and France).
All in all, great job getting this going, but you should really take it to the next level
Hope I wasn't too critical!
