Scenario: The Fall of the Republic

Overview
The year is 2157, and the glory days of the United States of America have come to an end. The once strong period of Pax Americana that consumed the world during the 2060's was a well, and it had run dry sometime in 2140 when over nine countries reached superpower status. Its military has taken a beating from the world's best to the world's seventh best, and its nuclear arsenal is undeveloped at best and completely outdated at worst.
