Nothing short of demanding N. Korea dismantle their weapons should be said during the talks. There should be no giving in to N. Korea. AT ALL. No compromise.
Hmmm... I think I'll leave the diplomacy to the diplomats. I'm sure they know what they're doing. It's not some all-or-nothing game. Anyway I'm in Seoul right now and no one here seems to give a crap about North Korea right now.
