In a photo released by North Korea's Korean Central Agency, North Korean leader Kim Jong Un (third from right) and other senior leaders attend a memorial service in Pyongyang, March 25, marking the 100th day since the death of Kim's father, Kim Jong Il. North Korea has been sending the world mixed messages since the death of the elder Kim.
Recent developments in North Korea are puzzling watchers of the "Hermit Kingdom" in both the U.S. and South Korea.
There are some signs of change within the new leadership in North Korea - and there are signs of resistance to change as well.
When he was in Seoul, South Korea, last week, President Obama said he didn't know who is calling the shots in Pyongyang, which is making it difficult to determine what's next for North Korea.
Even though things look calm on the surface, that's probably not the case, says Seong-ho Sheen, professor of international studies at Seoul National University.
"Any totalitarian regime, if history is any guide, cannot last forever," says Sheen. "I think North Korea cannot really avoid the fate of history. At one point it also has to change."
With the death of Kim Jong Il and the elevation of his son Kim Jong Un, it's natural to ponder whether one of those points might be now, says Bong-geun Jun, professor of national security at the Korean Diplomatic Academy.
"Now it's a kind of a testing moment ... whether really you can talk to North Korea's young leader or maybe we have to wait for some time," Jun says.
In February, North Korea said it would freeze its uranium enrichment and missile tests, and let international inspectors back in to keep track.
Another announcement came almost immediately: that North Korea is planning a rocket launch in mid-April, an action nearly the whole world is condemning.
Is this a sign of a split in the new leadership? Maybe. But more likely, says Jun, the North wants to send both messages.
"I think both Kim Jong Un and his leaders are making use of each other so that they can keep their system, or their state, alive," Jun says.
U.S. And China Respond
President Obama delivers remarks at Hankuk University in Seoul, South Korea, last week. During his visit, Obama warned Pyongyang against more provocative actions, at the same time reiterating the U.S. has no hostile intent toward North Korea.
Last week, Obama stepped into this diplomatic hall of mirrors. In remarks directed at the North Korean leadership, Obama said bad behavior would no longer be rewarded.
At the same time, he announced the U.S. has no hostile intent toward North Korea. This was something of a mixed message from the American side, according to Sheen.
He was warning North Korea not to engage in brinkmanship, yet trying to encourage moderate behavior and then later some reform, Sheen says.
The role of China is another piece of the puzzle. Frequently, the U.S. has appealed to China to prevail upon North Korea to stop its provocations. Repeatedly, the Chinese resist American pressure.
Last week, Chinese President Hu Jintao was also in Seoul, and he very publicly expressed displeasure with the North Korean decision to proceed with the rocket launch.
So will China do some real arm-twisting in Pyongyang? Not likely, says Sheen. It might show just how little influence China really has over the North Koreans.
"North Korea doesn't trust the Chinese completely. China doesn't like the North Korean leadership very much," Sheen says. "But simply there's a kind of common interest that binds these together, so that neither one of them [can] break away from this bilateral relationship."
Obama's Call For Unification
One aspect of Obama's trip to Seoul last week that was almost entirely overlooked was what he said about Korean unification.
In language that recalled Germany's experience after the Berlin Wall came down, the U.S. president made an impassioned appeal.
"The day all Koreans yearn for will not come easily or without great sacrifice, but make no mistake, it will come," Obama said. "And when it does, when it does, change will unfold that once seemed impossible. And checkpoints will open, and watchtowers will stand empty, and families long separated will finally be reunited, and the Korean people at long last will be whole and free."
For some South Koreans, like Sheen, it was something of a Ronald Reagan moment, recalling the former president's famous words - "Mr. Gorbachev tear down this wall." Sheen calls Obama "visionary."
"He can be seen from North Korea as very provocative, but I think he still wants to provide his own vision for the future," Sheen says.
Where things stand, practically speaking, is hard to say. It's likely North Korea will go through with the rocket launch. The U.S.will counter by withholding the food aid it pledged.
But North Korea has opened contacts with the International Atomic Energy Agency to allow inspectors back to monitor a freeze of its uranium enrichment program.
That in itself might be an indication of new flexibility on the North's part, despite the current tension.
