North Korean leader Kim Jong Un has pledged to develop additional military measures and allocate more strategic assets to respond to the buildup of US forces in the south, as the country prepares for a major anniversary parade. In direct proportion to the buildup of US forces in [South] Korea, our strategic interest in the region has also increased, and we have accordingly allocated special assets to key targets of interest, Kim was quoted in a report published by the state media KCNA on Sunday.
