"The best weapon against an enemy is another enemy" - Friedrich Nietzsche
The United States and North Korea have a strong relationship of animosity, it's been so for as long as people can remember. Year long phony wars and untrue threats plagued the two countries with mistrust and paranoia. Until the year 2018 rolled around and the limit was hit. It happened overnight, troops from both sides prepared for war. Jeremiah Dempsey was aching to go to war, to finally teach the Koreans a lesson.
The U.S. soon was the one learning the lesson. China had backed North Korea with an incredible weapon, we called it the mólyvdos Wind, or "Lead Wind". And it completely wiped out entire forces, almost vaporizing everything. Jeremiah wasn't "vaporized", but instead "displaced" in an entire new world. Now he's gotta deal with what comes after that. And also the enemies he makes.
