All Instruments of National Power Should Be On The Table When Dealing With North Korea. Dr. William J. Parker III joined Charles Payne on Fox Business News on May 25, 2018 to discuss efforts to denuclearize the Korean Peninsula. Dr. Parker said, “These are very normal procedures for these types of negotiation. (North Korea) realized that (President Trump) is unpredictable and that is good when you’re dealing with countries like North Korea… President Trump is willing to leave all of the instruments of national power on the table and that’s different from what we’ve seen in the past—diplomatic, information, military, economic, financial, intelligence and law enforcement.”
