The death of North Korean leader Kim Jong-Il has raised fears of turbulence in the nuclear-armed nation but observers said a dynastic succession is underway and that strife is unlikely for the time being.
Analysts said Monday's announcements on North Korean state media, which revealed Kim had died two days previously at age 69, made it clear his youngest son and heir apparent Kim Jong-Un is firmly in power at least for now.
But some North Korea-watchers cautioned of risks ahead if the young and inexperienced Jong-Un feels the need to prove his military mettle by deploying the kind of aggressive tactics that helped keep his father in power.
State media in Pyongyang have urged people to rally round the leadership of Jong-Un, who is aged in his late 20s, with the state news agency dubbing him the "great successor".
"The Kim Jong-Un era has already started," said Paik Hak-Soon of Seoul's Sejong Institute think-tank. "This clearly indicates that Jong-Un is already firmly in power, and all key officials under Kim Jong-Il have decided for the past two days since Kim's death to support Jong-Un as the new leader," he added. "The North's top guys have already sorted out everything, and the regime seems to be stable under the new leadership.
I don't expect any major turbulence or power struggle within the regime in the foreseeable future.
Little is known about the young man now expected to extend the Kim dynasty into a third generation, other than that he attended a Swiss school and reportedly likes skiing and Hollywood tough guy Jean-Claude Van Damme.
Kim Jong-Un had little public profile until his father suffered a stroke in 2008, forcing succession plans to be accelerated.
In September 2010 the son was handed senior ruling party posts and made a four-star general, despite his lack of any military experience. Since then, he has been constantly at his father's side.
Kim Jong-Il's powerful brother-in-law Jang Song-Thaek may act as the son's mentor as he finds his feet, say analysts who note that North Korea's elites have a vested interest in maintaining the status quo.
"For a while the military and Kim's family will try to uphold Kim Jong-Un as their leader and unite around him," said Baek Seung-Joo of the Korea Institute for Defence Analyses, adding that the North had fully prepared for Kim's death.
In recent years, Kim Jong Il tried to minimize the power of other older party members, often demoting them - sometimes even banishing them to the countryside - so they wouldn't form allies of their own and threaten his son.
