Virgil, people like you are what is wrong with the world. Have watched the trailer for other languages? The trailer awknowledges each nation in their language. In the Russian version, they use transmissions from the first launches, and from what I've read the same is true for the other languages (I don't understand French, German, or Spanish in the trailers even though I speak them).
In Star Trek, each 'nation' has semi-autonomy with in the United Earth (much like each US state has semi-autonomy with the US), and United Earth has semi-autonomy within the United Federation of Planets. In fact it has been stated many times that there are still nations on Earth (including the US, Canada, France, Britian, and the United States of Africa), so saying the shows or movies are an extension of the history of the United States is an ignorant statement.
One must also take into account, at least in terms of Enterprise, that most of the images used were historically accurate. They had the Wright Brothers, Chuck Yeager, the NASA Space Shuttle (not the Buran Shuttle), etc, not because they are American, but because they are the most widely recognized symbols of flight and space travel. I doubt that many people in the world even know what a Soyuz rocket looks like, or even know that Europe has a space program. They did show the International Space Station, and how it is supposed to grow.
It has never been estabilshed in canon as to where the Enterprise (NCC-1701) was actually constructed, be it in space or on the surface, but the dedication plaque has always said San Francisco, Calif. If you wouldn't mind paying attention, but San Francisco is the capital of both United Earth and the United Federation of Planets (with presidential offices in Paris).
Anyone who says that Star Trek is US-centric has never really paid attention to the show. Granted it may appear to the layman to be the case, but many people aren't even human in the shows. So Captains Kirk, Archer, Sisko, and Janeway were American (the last one was not suppossed to be). Picard was was French (with a slight English accent due to the death of the French Language), Checkov was Russian, Uhura was African (from the United States of Africa), Scotty was from Scotland, Hoshi was from Japan (or Brazil), Malcom was from England, Travis was from space, Geordi was African (from the African Confederation), Miles was from Ireland, Julian was a British Arab. The only show to be "American" was Voyager, hense everyone's distain for it.
Where do you come up with the idea that the movie is about the USA? As I said before, pretty much everything in the series has been based out of San Francisco, and you are just now having a problem with it?
Seriously, it is fiction, not the template for the future. If it bothers you, fine. I'll watch the movie twice to make up for you.
