A day after launching a long-range nuclear missile as a warning to the U.S. and South Korea, “around 800,000” young North Koreans signed up for military service and vowed to “completely wipe out” enemies and unify the Koreas, according to state media on Saturday.

The Rodong Sinmun report said the “Youth Vanguard rose up at once to join the war to defend the homeland and the war to destroy the enemy,” referred to in the article as the “U.S. Imperialists and puppet traitors [who] are trying to destroy our independence and right to live and develop.”
