In 2035, the unified Korean Peninsula acquired North Korea's nuclear weapons, entered the ranks of the world's five major powers, and Japan finally completed its nuclear development under the tacit understanding of the U.S., which seeks to rein in China and aggressive anti-Western Russian forces despite strong opposition from neighboring countries, including South Korea, as if returning to imperialism in World War II.
