Kim Jong Un has called for an "exponential" increase in North Korea's nuclear arsenal, including mass producing tactical nuclear weapons and developing new missiles for nuclear counterstrikes, state media said Sunday.
In a report at the end of a key party meeting in Pyongyang, Kim said the country must "overwhelmingly beef up the military muscle" in 2023 in response to what it called US and South Korean hostility, the official KCNA reported.
