Very lucky break? I’m not sure I follow.
I think the only way for Lee to extricate himself is to interntionally and without too much delay order a reprisal against the NORKs.
By “lucky break” do you mean the NORKs go ahead and oblige Lee and fire off another round of arty?
Actually I have one scenario: Kim Jong-il dies tonight, and wailing NK broadcaster shows up on NK State TV announcing his death.
