I think china is going to inherit the north Korean issue.
Gives the Chinese a few more thousand or so miles of coast line, a huge army, albeit underfed yet highly motivated especially under threat of U.S invasion.
The other question is, can the U.S afford another fight/war of say two to three months or longer...if they pull back from full nuclear assault. Plus there is an election coming and I don't know if Obama would risk starting a conflict, which the U.S has had a known history of, when his performance with other actions have been met with public and press negativity.
Of course the people their once over the grief and 'show' of respect, return to their own empty lives maybe some will start to lead a revolution, they will see this younger fat son...errr cruising the country in his car, two bottles of cognac, etc and this will trigger some reaction I m sure.
