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.
