North Korea has developed its methods over 60 years

Seoul: Just before Kim Jong-il died, the skies glowed red above sacred Mount Paektu and the impenetrable sheet of ice at the heart of the mystical volcano cracked with a deafening roar.
At least, that's the official account of the supernatural circumstances preceding Kim's death last Saturday at age 69, as relayed by the state-run Korean Central News Agency. The news agency is one of the chief propaganda organs tasked with building up the quasi-religious mystique around the Kims, North Korea's only rulers since its founding in 1948.
The tools for making the myth have been developed over two generations, dating back to Kim's father, late President Kim Il-sung. But with Kim Jong-il's sudden death and the ascension of his young son Kim Jong-un, North Korea's image artisans will have to do it all at warp speed.
Some of the hallmarks of the mythmaking machine in North Korea:
Legends
Kim Jong-il's official biography says he was "heaven sent," born in a log cabin in Mount Paektu while his father was fighting the Japanese.
"Wishing him to be the lodestar that would brighten the future of Korea, they hailed him as the Bright Star of Mt. Paektu," his biography reads.
Lore has it soldiers spread the news of his birth by inscribing the announcement on trees across the country — a practice that North Koreans continue today by carving the leaders' messages into rocks and mountainsides.
Soviet records, however, reportedly indicate Kim Jong-il was born the year earlier in Siberia.
The account of his death was just as mythic. His obituary in state media called him the "illustrious commander born of Heaven," and on Wednesday, KCNA said a Manchurian crane spotted in the city of Hamhung circled a statue of Kim Il-sung for hours before dropping its head and taking off toward Pyongyang. The crane is a traditional Korean symbol of longevity.
The mythmaking for Kim Jong-un has begun as well, with an editorial in the Rodong Sinmun newspaper calling him "born of heaven." However, details of his birth, and the accompanying legend, have not yet been revealed.
