Can this air defense cover a column of tanks and troops against our bombers and strike fighters when it crosses the DMZ?
Air power would dish out some serious punishment, but close to a million troops, a full corps of tanks, and over ten thousand artillery pieces all needing immediate suppression will overtax the air assets ability to respond. That like trying to hold back the tide with a bucket.
Aircraft need time to refuel, rearm, and get the pilots briefed on their targets. Meanwhile, the jewel of the south, Seoul, is a 40 mile walk from the border.
