I never imagined Dennis Rodman would help get this done.
Now back to reality, NORKS have been constantly putting out these little carrots for decades, usually negotiating some concession. There isn't anything new about this other than the reporting. Once they get to the table, like 2014, 2004, 1993, etc, the NORKS will make a huge list of demands that can't be met then walk away.
This is something they do every few 8-10 years or so. Madeleine Albright even got suckered into going there to help negotiate something like this back in 2000. Nothing became of it and it just emboldened the NORKS. The nutjob leader wants recognition and attention.
