North Korea says U.S. groups raise war threat

North Korea says the unprecedented deployment of three U.S. aircraft carrier groups “taking up a strike posture” around the Korean peninsula is making it impossible to predict when nuclear war will break out.

North Korea’s UN Ambassador Ja Song Nam said in a letter to Secretary-General Antonio Gutteres Monday that the joint military exercises are creating “the worst ever situation” around the peninsula.

He also said the U.S. has reactivated round-the-clock sorties with nuclear-capable B-52 strategic bombers “which existed during the Cold War times.” Ja said “the large-scale nuclear war exercises and blackmails, which the U.S. staged for a whole year without a break ... make one conclude that the option we have taken was the right one and we should go along the way to the last.”
