Juche has been the official state ideology of North Korea for thirty years.
 Kim Il-sung summarized the application of this objective to North Korea in a 1967 speech to the Supreme People's Assembly entitled "Let Us Embody the Revolutionary Spirit of Independence, Self-sustenance and Self-defence More Thoroughly in All Fields of State Activity":First, the government of the republic will implement with all consistency the line of independence, self-sufficiency, and self-defence to consolidate the political independence of the country, build up more solidly the foundations of an independent national economy capable of insuring the complete unification, independence, and prosperity of our nation and increasing the country's defence capabilities, so as to safeguard the security of the fatherland reliably by our own force, by splendidly embodying our party's idea of Juche in all fields
 North Korean sources attribute its conceptualization to Kim Il-sung, the country's founder and first leader
