The nations of the world believe that the United States of America or the USA is an immature, foolish boy who thinks that everything comes to him with no problems at all. But is that all they know about the United States of America?
Well, you look back a little deeper into US history you might just find something you would not believe, a family that stands against time and separation for nearly six hundred years, a love that could never fade away because of time, and a father that can protect, serve, and love his family even when others belittle him for his actions.
Try looking at it as a coin, coins have two sides, a heads and a tails, if you only see the heads and not the tails of a coin, you can't win a coin toss with only heads. Because you need to think of the endless possibilities of the coin landing on either heads or tails, not just one of them.
So to help the world understand what the nation of freedom really is and what he is all about, they, the Ancients, collected the journals, diary entries, and notes about all the nations of the world to open up their eyes to the truth.
