Speaking to NowThis News, Carnegie's James Acton discusses U.S. concern over the trajectory of North Korea's nuclear development. Sensing a threat from the U.S., Dr. Acton explains, North Korea likely desires nuclear weapons capability for deterrence purposes; such capability is also a useful way of trying to coerce concessions from Japan, South Korea, and other countries. While Dr. Acton predicts that North Korea will harness the ability to development an intercontinental ballistic missile that can reach the U.S. in the next several years, direct war between the U.S. and North Korea is unlikely, though not impossible.
