I agree this should not turn into a pre-emptive military strike.  But, you can bet your tail they have a plan.  I can guarantee you our air defense system is turned up to 11 right now.  And, this wouldn't be one of those boots-on-the-ground thing to lead the way.  Did you follow what happened in Desert Storm?  That was an air campaign that was carefully planned out and worked fantastic, minimizing US casualties.  Btw, my 35th Wild Weasels were second ones in to squash the Iraqi radar.  :-) 

Anyway, we spend far more than any other country on our ability to kill, and it shows.  It's why I have so little fear of these supposed threats on the planet we have to supposedly attack.  They're nothing compared to our capabilities.

Kim might get lucky here or there if he goes full stupid and tries sending a strike our way.  But, that first will be his last.  Guaranteed.
