The United States of America is a federal republic consisting of 50 states and a federal district. Formed from 13 colonies fighting against the British, the United States rose to become a global superpower in the twentienth century. Following the 1989 asteroid impact, the USA found itself caught in an economic recession, which lasted until the early 2000's.
The United States was one of the countries most affected by the asteroid collision. On March 22, 1989, the asteroid landed only several dozen miles away from the East Coast. The impact caused an earthquake that was felt all the way to the Midwest. Barely twenty minutes after the impact, a tsunami over 30 meters high strikes the East Coast, flooding cities such as Boston, New York City, Jersey City, Dover, and Washington, D.C., as well as many more. Approximately 10-20 million people died as a direct result of the impact.
Most states on the East Coast declared states of emergencies. A massive repair and assistance operation was quickly undertaken under President Bush. When Iraq invaded Kuwait in 1990, the U.S. mostly ignored it as they focused on recovering. President Bush became unpopular due to his handling of the disaster. In 1992, Bill Clinton beat him in the presidential elections. Clinton struggled to improve the economy and barely won re-election. The dot-com bubble was greatly diminished. Clinton became very unpopular, and he was forced to resign following his impeachment. In the next election, George W. Bush beat out Al Gore by a slight margin. The economy still mulled along, before suddenly picking up all of a sudden in the early 2000's.
As a result of the United States' non-involvement in Iraq, the 9/11 attacks never happened. As such, neither does the War on Terror. The Cold War extended for several more years as the Soviet Union struggled to stay together. Saddam Hussein remains in power. The scars of the meteor impact remain in America to this day, with many cities on the East Coast never fully recovering.
