Areas of the US most likely to be hit by nuclear strikes.

Barneyboy,

Agree with you here. If DPRK launches a multiple-missile "test" towards the waters near Guam, they would have to pass over Japan. The Japanese have been equipped with THAAD anti-missile systems provided by the US.

If any of the missiles get through the Japanese missile defences, there are additional seabourne systems deployed on US Navy ships of the Pacific Fleet, as well as on Guam.

I would fully expect the missiles to be shot down and the debris recovered to determine is there were any weapons aboard.
If the missiles would be indeed armed, whether nuclear or conventional, the US response will be appropriate. If the missiles prove to be unarmed, then THAAD passes a real world operational test and the DPRK loses face.
