Ms. Kim said ​that North Korea would respond ‌in ways that made Japan feel that its security has been exposed to greater danger. Ms. Kim also accused the ‌United States of enabling Japan's military buildup by supplying Tomahawk missiles, ​modifying vessels for their operation and supporting the missile tests. Ms. Kim, who heads the record-keeping department in North Korea's ruling party, said Japan's acquisition of long-range strike capabilities effectively placed North Korea and other neighbouring countries within ‌range. To counter Tokyo's military activities that may pose a potential threat to the security of North Korea, Kim said Pyongyang "will set up additional military options," without elaborating. Analysts said Pyongyang is seeking ​to portray Japan's military modernisation as a direct security threat to justify its own weapons development.
