Don't get me wrong I believe that Kim Jung-Un is very dangerous and the path taken by North Korea is very dangerous and worrying. I just don't believe that military action is the answer for both sides. All possible diplomatic avenues need to be pursued included taking the US out of the diplomacy and replacing them with someone North Korea is prepared to listen to and maybe compromise If NK does fire first the US will with good reason retaliate in force and the outcome is going to be horrific with a very high regional death toll.
Id be fully ok with that
But I feel NK has been running on far too long a reign for too long. They say they will talk, the US say they will talk, but the new bottom line now is, no nukes is non negotiable from NK, and keeping nukes is non negotiable from the US. While this is a NK vs SK/Japan issue, the extent that NK has developed a nuclear capability makes it everyones business. Advising that we will fire 4 missiles to hit 25 miles from Guam now makes this a US direct issue.
I cant say what China thinks as they also did little to stem NK, although being friends makes that quite easy, and being anti US. Had NK kept up with their fairytale commentary and bitched at SK and Japan, that would have been one thing, but they made the mistake of stinging the dog, the US. They are now fully in this problem, not just a supporter of SK and Japan. They could take action based solely on the NK direct threats to the US, so thats IMHO a new can of worms. The US is not near the region, China is, China's mistake as well by letting it go this far.
