North Korea detains U.S. soldier who allegedly fled mistreatment and racism in Army

U.S. Army Private Travis King crossed into North Korea in July while on tour near the border.
North Korea claims King fled due to mistreatment, racism, and inequality in the U.S. Army and society.
The U.S. cannot verify North Korea's account and aims to ensure King's safe return.
King had faced disciplinary action in South Korea prior to crossing the border.
North Korea may seek to use King's case for propaganda or leverage in negotiations.
