"Strong and Prosperous Nation" is a political slogan in North Korea which originally described the main policy objective of the country's second supreme leader, Kim Jong Il. Kim Jong Il argued that the military-first policy of Songun was necessary to turn North Korea into a "strong and prosperous nation". He further argued that such a monumentous goal could only be achieved by strengthening the country's commitment to the core principles of Juche in the areas of ideology, politics, economics, and defence.
