They blatently have no long range nukes. They would surly have used them by now
Either way I am incredibly interested in the situation that will unfold. Whilst you guys have your scientific discussions, I specialise in Politics and I am incredibly interested in the upcoming scenario

Regardless of the Nuclear Issue, both China and Russia (similar to Iran) still harbor some degree of support in North Korea. Russia is more than likely upholding its public disregard for Americas International hegemony, but the China support is interesting, being a similar Communist Nation (albeit with a free market economy of sorts, something which Kim Jong-Il purportedly inquired about many times as to how it could work).
The original successor actually lived in China (the same guy who was arrested for trying to go to Tokyo's Disneyland), and ultimately was China's safeguard, you've now got this guy of whom we know absoloutely nothing regarding his intentions and political views - apart from the fact he loves Michael Jordan. Very interesting

Obama's policy of 'Strategic Patience' which effectively means do nothing is ultimately going to be tested. The entirety of South Korea is on profound red alert - the sinking of their warship and the shelling of an island being the new sucessor effectively flexing his military prowess to the people, will be interesting to see what happens next year.
South Korea cannot move against them because of Russia and China, neither can the US.
Whilst 2011 was the year of massive political upheaval on a global scale, 2012 will be the year when such upheaval will be acted upon
