What about our ASM-135 ASAT missile or other weapon systems we have ?What about our X-37B ?
We HAVE the capability.
What we've lacked ... is the "WILL" to USE it !
But Trump does NOT have that problem.
Do you think the artillery south of the DMZ that the ROK has, as well as the United States Army has, is just going to sit there and allow Seoul to be destroyed ?
What do you think their FIRST targets will be ?
Our's as well as the ROK's artillery are already 'dialed in' on those North Korean artillery sites, as well as the barracks that house the North Korean soldiers that man those sites?
How many of those north Korean Artillery sites are controlled by electronics (computers) ?
Do you know about CHAMP and its capabilities ?
Counter-electronics High-powered Microwave Advanced Missile Project (CHAMP) ( 2:17 )

Do you know about MOP ("Massive Ordnance Penetrator").
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.
