Then the JDAM's, Big BLU's, and cluster bombs rain from the sky. Cruise missles strike with three meter accuracy.

Repeated waves of the most intense Air strikes imaginable drop from B-52' and B1-B's. Within 48 Hours, ground troops come. Then M1-A1's, Warthogs and Apache's start in. Night Vision, Vulcan armed gunships, Precision weapons of all sorts. Deadly accurate Artillary, tactical rockets. There won't be a city worth mentioning north of the DMZ left. Supply lines will be destroyed, re-supply depots will be craters. CNC will cease to exist.

It will be horribly bloody, an awful lot of people will die, civilian and military. Korean and American - the South will suffer extreme devestation.
And Pong Yang (SP?) really doesn't care. They will revel in attempting to wipe Seol off the map, and slaughter thousands of their own countrymen, just as every other Communist State has done with conquered territory since Stalin marched into Germany. Like Hi Chi Mihn and Pol Pot, they will start an orgy of killing, 'cleansing' the locals of the 'Elite' intelectuals.

I honestly believe they have not the slightest idea of what the US armed forces are capable of. Even having seen the news from Iraq and Afghanistan.
And I believe they grossly overestimate their own capability.
