United States of America

The United States of America (USA) is a Constitutional Republic located on the North American Continent, between the Pacific and Atlantic oceans. Starting In the early 20th century, the US became a major world power, one of the first located outside of Eurasia. The United States is the only country visited by the player in all 3 Deus Ex games.

Events in Deus Ex games
In Deus Ex: Human Revolution, The US and it's government appear to operate much like they do in the current day. Sometime during or after the events of Human Revolution, the Statue of Liberty, a major American landmark, is bombed. By the 2050's, the US government faces heavy corruption between the Illuminati and Majestic 12, but still operates somewhat like it did in the early 21st century; Government organisations such as UNATCO and FEMA still exist, a President is in office, and some form of Senate is referred to.

Before the events of Deus Ex, in 2042, a weapons law called the Sporting Weapons Act of 2042 moves conservatives and weapons enthusiasts from every state to form the NSF, a terrorist group aimed at "liberating" the American Northwest. Some states, namely Oregon, Montana and fringe groups in Texas, secede from the United States in reaction to the act, and the NSF continue to operate for another 10 years, even after General Leon Woods dies in 2045. America will see several disasters over the following decade; an earthquake in California will make the entire state a disaster zone, a major Economic recession will take place, and an epidemic of the Gray Death will begin.

At the End of Deus Ex, JC Denton inadvertently destroys the Aquinas routers, disabling the internet and throwing the world into a two decade long economic Collapse. In Deus Ex: Invisible War, the United States are strangely never referred to. The player visits an enclave in Seattle, private property owned by the WTO, which has its own economy and law system. When they visit the Lower Seattle slums, no one mentions the US either. Late in the game, the player will visit Liberty Island, though it is only inhabited by bums and hostile characters. It is entirely possible that the USA disintegrated during the Collapse, though records state that the WTO chartered the land in 2070, implying that there is some form of Government in the 2070's.
