Caveat that I have not played the games, but taking the series at face value they are highly US-centric like most Hollywood productions. It makes no sense arguing on the basis of the series alone what they are going with in this regard, since all the action takes place in the US it is pretty much the scope of the universe, just like in many Americans minds. I tried to make a disjoint point, that was based on how I would interpret it with complete disregard to whatever is canon to the story as a whole, taking what is presented in the first season of the series at face value.

To put this into context with Star Trek, I also find it really boring and non-immersive whenever they hold 21st century America in special consideration. It is just such an obvious way to make a comparison to current state of affairs in one particular country, placating preferences of current pop culture, which is redundant anyway since all science fiction is a universal critique of the current state of affairs anywhere simply by showing a future alternative. A hypothetical sudden end to US hegemony is actually a valid way to make the current US affairs leading up to it special with respect to the future development of mankind, and not just a boring move for views.
