N Korea’s Kim Jong Un calls for ‘exponential’ expansion of nuclear arsenal

North Korea unveiled a new facility to produce nuclear bomb fuels as leader Kim Jong Un called for an 'exponential' expansion of the atomic arsenal. Kim said production capacity for weapons-grade nuclear material has more than doubled in five years. He justified the expansion due to worsening security threats and a long-term confrontation with 'the most ferocious enemies', reaffirming the policy of nuclear deterrence. Analysts view the visit as a message that denuclearization is not an option before potential diplomatic engagement.
