How will the United States(timeline varies from maybe after 1918 till 2019 AD) affect The World when these Yankees having different races of humans being so high tech and war like nature? Like their military have the ability to fly on fighter planes to maybe fighter jets and their top of the line weapons manufacturers making everything that outclasses The World and even the Faerie species(before they are being hunted down).
Hope anyone can answer my what if question.
