There aint going to be a land war in North Korea and if there is going to be one, its "Game Over Man"... Even if we shoot all his missiles down, whats to stop him from detonating nukes in cities that we would take in a land war?
Also if you park enough Aircraft Carrier Groups off the Korean coast, it will make China antsy...
The best we can hope for is that there is a quick coup that removes Kim, and even that possibility is scary.
We ignored them for far too long which allowed them to build themselves up to this point.
Sooner or later, someone is going to have to "Pay the Fiddler"
"All his missiles" ... They could maybe get "a nuke" through... maybe. They cannot lay waste to California, Japan and S. Korea.
