There is more to it than that though, what do the North Koreans actually want? They want a federal Korea with two systems, two leaders, united as one country and with a seat at the U.N. for that one country. A united Korea would be a true world power within a generation, with GDP and population that would outshine all but one of the security council permanent members. None of the North's weapons point at the South, I think the North just want the USA out of the peninsula and for there to be an orderly reunification process without external interference.
The South also expect unification to happen one day, it not being a hostile takeover.
A united Korea with nuclear weapons would be deserved of veto rights at the U.N. and I don't believe the U.S. wants someone else at the top table. So a war is very much being fought, Korea can't be allowed to be united!!!
It is easy to condemn the crazy Kim guy and slag off North Korea but I think that we are the ones propagandised against as much as them. In all my decades of watching and reading the news I have not once been told what the goals of the respective sides are regarding unification. None of these newsreaders have told me the implications of a united Korea either. I wonder if the U.S. is at war to keep Korea divided, as opposed to keeping their South Korean buddies safe from those crazies up North.
I also think that North Korea is okay to censor out capitalism in its many advertised forms from the web since they are very much under siege/at war with the U.S.A. Would you want your people to be using electronic devices that the CIA could 'Arab Spring' a faux revolution from? Would you want your population drowning in fake news? Is it really that bad to just ban the mainstream media?!? To Ad-Block everything, for everyone? Is access to Facebook or being able to tweet now a human right?
If the international community wanted to resolve North Korea it could be simple - unification - let Korea become a united country with the U.S. taking their tanks out, sorting out their issues by themselves with those pesky nukes swapped for a top seat at the U.N.
