America Stranded in a Fantasy World

Most thought World War 3 would bring an end to the world as we know it, and the superpowers of the world knew this as well. Yet when the prices for basic raw materials continued to rise, it was China who first took the steps to war. A war for untapped resource deposits in Africa no less, and The United States and The Russian Federation, moved to counter. Set 5 years after the resource proxy-wars in Africa in the year 2040. A new Earth eases back into peace. China with what little land it gained in Africa turns inwards to combat the growing instability of the border regions, a military coup in Russia marks a new chapter in its own history, and The United States comes out leaving beaten and bruised, but not defeated. But on June 15th, a world-altering event transpired. It only lasted for a fraction of a second, however it did more damage than any war could do. The United States, with all its power and might, had… well, vanished. The United States, a once thriving nation of 380 million people, now just forest, plains, desert, and mountains. Now, the 49th President, President John Dresden. Is forced to lead a nation scattered across a foreign world, a shaken economy with the foundations themselves cracking, and an anxious nation. While on Earth, mass hysteria over the vanishing of The United States pushes world leaders to their breaking point, and people to do things they wouldn't even thought of doing just a few weeks prior. Will this be what finally causes Earth to remember its past, or be what finally brings down The First Realm?
