North Korea touts “nuclear war deterrence” with submarine cruise missile test amid U.S.-South Korea drills

Seoul, South Korea — The South Korean and U.S. militaries launched their biggest joint military exercises in years Monday, as North Korea said it tested submarine-launched cruise missiles in an apparent protest of the drills it views as an invasion rehearsal. North Korea’s launches Sunday signal the country likely will conduct provocative weapons testing activities during the U.S.-South Korean drills that are to run for 11 days. Last week, North Korean leader Kim Jong Un ordered his troops to be ready to repel its rivals’ “frantic war preparation moves.”

The South Korean-U.S. drills include a computer simulation called the Freedom Shield 23 and several combined field training exercises, collectively known as the Warrior Shield FTX.
