If NK does launch an EMP attack... Make no mistake there would be an immediate nuclear strike on NK.. I'm guessing 2/3 high target attacks. It truly would be WW3.... NK would then strike SK and more likely Guam.
IDK if China would respond or not... If so then it would truly be the SHTF scenerio so many of you long for.

If our infrastructure was damaged that bad. Our carrier strike force would be immediately recalled to protect our shores. Any and all aggression would be met with tactile nukes as we would be a wounded duck.

For those who don't know...the "silos" that hold our ICBM'S are self contained and don't need "grid" power to operate.
