The real issue is the North Korean artillery. That’s the hard egg that has so far been impossible to crack. The million-man NK army is honestly really neither here nor there ...it is a credible military, and they have an interesting approach to special forces, but the US military would absolutely chew them up. The use of massed armies against the US would not be prudent. The problem though is the over 10,000 artillery pieces aimed at Seoul, and the genesis of that problem is that it is (currently) not possible to neutralize all that artillery before Seoul is razed to the ground, the SK economy hit hard, and over a million people dead. That’s the real issue ...NK would be defeated, but not before they took Seoul with them. When that problem gets a solution then that is the day the KIM family will lose its hold over Pyongyang.
Totally agree - Seoul would be rubble. My comments were based on the assumption that if we allow the artillery to be a deterrent against any action, we have conceded that the NORKs are untouchable and have won - the flip side is that, while they cause a lot of initial damage, they can be finished off for good.
