Two points:
1. An EMP alone is not enough to prevent retaliation against North Korea. China would have to help. Otherwise that would be suicide for North Korea.
2. America may be the strongest, but it is not the only military power which would strike back at them. If taken seriously, there is this little thing called SEATO. There would be at least a half dozen other countries North Korea would have to be ready to fight.
... If taken seriously, there is this little thing called SEATO....
The SEATO organization folded in June, 1977. But, a treaty like that
Isn’t needed to smack the little fat boy.
“SEATO”
Not to mention NATO, for what ever that is worth.
There will be nothing to fight. Very shortly after America's ICBM missile subs become aware of things, the entire Korean peninsula will cease to exist. An EMP attack on the North American continent will NOT eliminate retaliation. I doubt that the NORK nomenclatura is that suicidal.
Fortunately, with President Trump, we won’t have to wait for an attack to deal with the fat NK maniac ... a “slipperly slope” to be sure.
