South Korea says North Korea made huge concessions in nuclear negotiations and is willing to talk to the US about disarming, but North Korean media mentions no such thing.
This points to a few possible strategies North Korea may be playing out, and they range from innocent to sinister.
The US responded to North Korea's talk of disarmament with cautious optimism, but stressed that use of military action to force Pyongyang to denuclearize is still on the table.
North Korean media has been very hushed about historic talks between South Korean officials and Kim Jong Un, which ended with representatives from Seoul declaring Kim had made massive nuclear concessions.
North Korea's most widely read domestic paper Rodong Sinmun made no mention of Kim's reported wish to denuclearize on its front page on Wednesday. On page six, the paper talks about North Korea as a "responsible nuclear power...preserv(ing) the values of parallel development of economy and nuclear weaponry," according to NK News.
The talk of growing the economy and nuclear program at the same time is one of Kim's consistent messages, and certainly doesn't acknowledge the massive about-face the South Koreans said he made during the talks.
In another North Korean publication, meant more for international consumption, Pyongyang bashed the US in its typical way, saying the US was "openly pushing ahead with its preparations for igniting a war of aggression in an attempt to reverse the atmosphere of detente on the Korean peninsula," according to the Wall Street Journal's Jonathan Cheng.
The incongruity between South Korea's reports of the negotiations, wherein Kim reportedly expressed a will to denuclearize and talk to the US, and North Korea's media, which continues to discuss nuclear development and the US as an instigator of war, points to a few possible motivations driving Pyongyang.

'At a very young age, he was able to assume power. A lot of people, I'm sure, tried to take that power away, whether it was his uncle or anybody else. And he was able to do it. So obviously, he's a pretty smart cookie,' Trump told CBS News.
The president also said he'd be 'honored' to meet with the North Korean leader.

The most innocent explanation would suggest that North Korea does not yet want to publicize its concessions, and is awaiting a US response before talking openly of them to avoid potential embarrassment if the US rejects the concessions.
Or maybe, according to Yun Sun, a North Korea expert at the Stimson Center, is that South Korea oversold North Korea's promises. "South Korea has an innate interest to provide the most benevolent interpretation of what North Korea said," Sun previously told Business Insider.
Another, more sinister motivation for Pyongyang could be driving a wedge between the US and its ally South Korea by exposing differences between the two countries' North Korea policies.
In South Korea, the government has sought more engagement with the North and remains exposed to the brunt of Pyongyang's military force if war breaks out, whereas the US has expressed a resolve to let North Korea wither under sanctions or go to war if necessary.
