United States of America

The United States of America—also referred to as the United States, the U.S., the USA, and America is a federal republic of 50 states and one federal district.

The country shares a land border with Mexico and Canada. It is also bounded by the Pacific Ocean as well as the Atlantic Ocean.

The country has been the target of many terrorists and, although most terrorist attempts have been stopped, there have been several successful attacks such as the September 11th Terrorist Attacks, the Nuclear Weapon Attack, the Cordilla Virus release, the abduction of Secretary of Defense James Heller, the meltdown of a nuclear power station, the destruction of Air Force One, and the assassination of Former President David Palmer.

All these events have lead to tough new security measures across the country and the creation of several new organizations such as the Counter Terrorism Unit.
