Th Real Threat-North Korean Artillery

The KPA keeps a lot of artillery. And when I mean a lot, I MEAN A WHOLE LOT! US intelligence estimates that North Korea holds a total of 10,000 artillery weapons, more than half of them can reach Seoul. This would cause thousands of dead civilians lying in the streets and mass destruction done to Seoul. Carpet bombing wouldn't entirely silence all of those guns. It would get rid of a whole hell of a lot, but there will still be some artillery they missed. South Korean intelligence says that it would take 3 days to completely silence KPA artillery! 3 days of constant bombardment! You can ignore those missiles they have, which would be shot down, their Air Force is in shambles, and the Navy...... well let's not go there. The KPA is made up of crude 60s Soviet tanks, aging and ineffective APCs and old artillery systems. It cannot match what South Korea has to offer, which includes the latest in tank, APC and artillery desgins. Obviously it seems that North Korea would want to do some damage before going down, and North Korean resistance after occupation would be tough. By then the US army would already have experience in urban warfare, and a program similar to the de-Nazification process that took place in WWII. When allied forces occupied Germany there was a 2-year resistance campaign led by Nazis, but it lost momentum after the de-Nazification process took place. So hopefully rhe same thing could happen in North Korea.
