Do:
1) Coordinate all steps with ROK, and keep Japan and China in the loop. This is vitally important. Don't "go it alone."
2) Extend our condolences “to the people of the DPRK upon hearing the news of the death of Kim Jong-Un.” Keep it simple.
3) Reiterate USA commitment to the Singapore 2018 Joint Statement. Specifically....
5) PRIVATELY remind DPRK leadership that the security of that country’s nuclear and missile assets -- i.e. preventing any use or transfer of those assets -- is a matter of "grave concern" to the United States. We will act decisively, if necessary, to protect our security.
6) Reiterate offer by USA to work w/DPRK to address humanitarian needs created by COVID-19 pandemic on strictly humanitarian basis, without political conditions.
7) quietly intensify intel gathering. Focus on non-proliferation threat; export of nuclear material or expertise
DON'T:
1) Say or do anything that could be construed as threatening DPRK — e.g. no military alerts or maneuvers, no force augmentations, no destabilization or propaganda efforts.
2) Don't praise KJU as a "good guy" or as "my good friend." He is NEITHER.
3) Don't lionize Kim or speak of “special relationship” between Trump and Kim. Don’t personalize this. If anything, keep distance
4) Celebrate this as a chance for DPRK “to move in a ‘new’ direction.”
We want DPRK to do what it promised in Singapore. If we are very fortunate, a new leadership MIGHT be more willing than Kim to do that (although I very much doubt it). But....
There are a couple of other things we SHOULD be doing in light of KJU disappearance from view.
We should also drop the blame game with China on COVID. China holds much sway over events...
