It’s not the first time that I said this, but EMP them first.
We'd have to drop leaflets telling them they've been EMP'd.
Won't work. They've only got one light bulb in the whole country, and it runs on two D cell batteries.
Having never used an EMP against an enemy, little is known about the weapon's range & effectiveness. Used over NK, it could also affect China, SK, Russia, & Japan.
This is a first strike, nuclear attack on the REGION. China and/or Russia will immediately go into nuclear crisis mode & the world could be minutes from global nuclear war. Do you trust Putin & the Chinese to ignore the use of nuclear weapons IN THEIR BACK YARD? Or will they respond with EMPs of their own?
Looking at a nighttime satellite image of NK, an EMP is a waste of technology, given that it doesn't affect candles & cooking fires.
However, a Russian or Chinese retaliatory EMP strike on the USA would be devastating, blacking out a huge part of the country, placing millions of people at risk of death from thirst & hunger. Thousands would die immediately from being cutoff from life sustaining devices. Communications, transportation, & commerce in the affected area would stop instantly. The enormity of the damage would be so great that any government effort at rescue & relief would be like a fly giving CPR to an elephant.
So, in an effort to kill a fly, let's not use the shotgun that might upset the neighbors. Rather, let's use some very precise weapons that will scare or blast the underwear off the little fat fool; AND remind our more potent enemies that we can still kill a fly at 10,000 miles range without making a ripple in his toilet bowl.
IF you can figure out how to get an EMP with an effective radius big enough to affect most of the DRPK without hitting Seoul or the PRC as well.
Would they even notice?
Ironic, in view of the nighttime photographs of Nork from space...
