SAM, you're back. Glad you had a change of heart from post #347!
Kim Jong Il, did not die of a heart attack, it was a CIA assassination. His son will almost certainly seize the opportunity to have a go at the South, hoping that international focus will be split between his actions and Iran. I would expect a border crossing any day now, although the South's high state of readiness will certainly halt them fairly quickly. That will be when the North has to fall back on its nuclear capability and will select specific military targets, not civilian ones. Now, the only question remaining is how will the US respond, especially with all those US personnel there?
