Comment: No more "drawing a red line or a line in the sand".  It's getting embarrassing since neither Obama nor Trump really meant it. The big problem with teaching Kim a lesson by attacking is that the U.S. has 26,000 or so American troops in S.Korea within U.S. Army and Air Force bases.  If Kim retaliates by attacking S.Korea, many of our GI's will die.  That will lead us to annihilate Pyongyang and we will be called the aggressor. The only practical way is to strike from within North Korea, with internal "kill Kim" assassins.  Money, a great deal, talks.  Do to Kim like he did to his half-brother.
