SEOUL, March 18 (Reuters) - North Korea claims that about 800,000 of its citizens volunteered to join or reenlist in the nation's military to fight against the United States, North Korea's state newspaper reported on Saturday. "The soaring enthusiasm of young people to join the army is a demonstration of the unshakeable will of the younger generation to mercilessly wipe out the war maniacs making last-ditch efforts to eliminate our precious socialist country, and achieve the great cause of national reunification without fail and a clear manifestation of their ardent patriotism," the North's Rodong Sinmun said.
