Possible Summit Dilemma

What if the North Koreans seize Donald Trump during the upcoming summit and refuse to give him back until we get rid of our nuclear weapons? Knowing these weapons as bad as chemical ones, failing to discriminate between combatants and noncombatants (and therefore illegal), we would naturally wish to comply. However, we would not want to appear weak and appeasing. The dilemma might be compounded by photos and videos of Kim leading Trump around on a leash, perhaps on all fours and getting a scattered kick in the ass. We better be on our toes.
