United States of America

The United States of America (or simply the USA) was once the most powerful country in the world before the outbreak, leading the world in military, economic and political power. However, once the zombie outbreak hit in full force and the public realized the severity of the situation, the country was brought nearly to the edge of collapse, with every element of pre-War America, from the culture to the military strategy, hindering or hurting efforts to contain the outbreak. It was only after the government and military sustained major reforms did the country finally hold back and ultimately destroy the zombie threat in America.

During world war z
After the first widely-known outbreak occurred in South Africa and subsequent outbreaks beginning across the world, the US government still largely ignored the outbreaks and somewhat downplayed them, as they felt there were more important matters to focus on. While the White House did implement phase one of the US military's contingency plan, phase two was shelved for the time being for the government. Additionally, the release of the Phalanx drug, touted as a cure of sorts to the outbreak, created a false sense of public security to the American public until it was exposed as a fake by journalists and multiple outbreaks occurred in middle-class neighborhoods, leading to the Great panic.

As the outbreaks spread and people desperately tried to leave the cities and get somewhere safe, millions were trapped in cars on highways between cities or on boats drifting out at sea, leading to many becoming prey to the zombie herds. Some celebrities and rich people, on the beaches of New York City, attempted to create their own safe zone with state-of-the-art security and facilities, but the zone was eventually overrun by desperate people looking for a safe place to live. The military, looking to quell the panic and show that they were still in control, set up a defensive position at the city of Yonkers just outside New York City, where the soldiers were outfitted with the best vehicles, technology, weaponry and equipment the military had to offer, where dozens of reporters were stationed to witness the military's so-called 'decisive victory.' Unfortunately, the battle was a complete and utter failure for the military, with the military force being decimated and the city being completely overrun.

Eventually, the government opted to abandon the eastern half of the country, creating a safe zone to the west of the Rocky Mountains. News Media and the Government told people to head to the Canadian Arctic as zombies cannot survive the freezing weather. This inadvertently led to the deaths of 11 million people through starvation, disease and hypothermia. Within the Western Safe Zone, the government underwent massive reforms.Eventually, they began the reclamation campaign and succeeded.

Current status/post outbreak
The US has been free of zombies for about 12 years, but is still rebuilding. Cities are now designed to be far more secure, the military has expanded and almost all energy and food are generated from local sources. The country is in an economic recession and continues to fight zombies underwater using special Military units.
