FIRST, We take out their satellites. (ASM-135 ASAT missile)
Second, we zap them with EMP Cruise Missiles, radar jamming and chaff. (Counter-electronics High-powered Microwave Advanced Missile Project (CHAMP) )
Then here comes it ICBMs.
Then the all out strike begins. Kim Jong-un gets a MOAB suppository.
Then we launch every aircraft in the region that’s supersonic, including South Korea’s fighters and bombers, to cross into North Korea from all directions, to overfly low level at Mach One PLUS, to bust every piece of glass in North Korea.
Then we firebombs the place to ashes.
The only real transportation system North Korea has is the railroads, so they get blown to smithereens.
And that’s just the start of day one.

Gosh...sounds good on paper. But no war nor battle was ever won on paper. After the first shot the whole game changes dramatically. No country is going to just stand there and take whatever you want to do to them. Unless he’s a total idiot, Kim will be no where near where that MOAB lands, and they are known to have enormous underground complexes. What are you going to do about them?
The biggest game changer of all is the fact that China and Russia have alliances and commitments to NK which they may well decide to honor when “we firebombs the place to ashes”, and “KILL ANYTHING LEFT ALIVE NORTH OF THE DMZ !” And when the second strike hits, how are you going to deal with the hundreds of thousands of NK and Chinese ground troops sweeping through SK?
I wouldn’t count on a quick clean victory. Asians are a thoughtful and patient people. I’m sure NK has a plan, another plan, and a couple dozen more in case those don’t work. Any military conflict is going to be a complete FUBAR.
