Ummm no.
To start they have an active an effective cyber warfare program. Their electronic warfare capabilities are advanced, specifically in GPS jamming. You know the jamming that makes our "smart" bombs really dumb.
Their missile capabilities are some of the best in the region. They have a respectable air force with over 700 combat aircraft (something we never contended with in Iraq), over 4,000 tanks, over 5,000 rocket launchers, 11,000 air defense guns and over 10,000 anti-tank guided missiles. They have the largest special forces capabilities in the world along with the largest submarine fleet. Much of their equipment is modern, Soviet made gear.
And of course the aforementioned artillery capabilities that could level Seoul within a day and that's even if they didn't use their chemical weapons or nuclear capabilities.
Lastly they have the Korean soldier. Can't even compare the typical Iraqi soldier of 1991 with today's North Korean soldier. They are a hardened and dedicated people that borders on fanatical. The Iraqis surrendered in droves.
It would be anything but a cake walk and occupation? Forget it. Never going to happen. The terrain alone makes Afghanistan look like Romper Room.
We've learned these lessons before.
