The 15-zip UN vote was a huge blow on the diplomatic/economic side. Now let’s make the sanctions hurt by intercepting any ships attempting to elude the sanctions, in international waters, of course.
Send disinformation in the form of forged letters from perceived NK allies such as Iran that will spoil relations between the two countries. This was a common Soviet tactic during the Cold War.
Cripple the two satellites that pass over the USA longitudinally every day. Do it covertly. They need to be blinded, and considering they’re in ideal orbits for an EMP, this needs to be a priority.
Organize an ocean blockade positioned in international waters, hopefully a U.N. action.
Try some unconventional scare tactics — fly a couple of B-2’s over Pyongyang at high altitude, then boast to the world that the Norks can’t do anything about it.
Take covert or clandestine action against their military assets.
Announce Kim’s location on a daily basis — exact coordinates. This would send a message that he’s personally going to be targeted in the event of hostilities.
Broadcast “The Interview” over the air into NK with high-wattage signals around the clock. Also broadcast re-runs of “Girls”.
While all that is going on, we take out the Pueblo, which should have been done years ago.
