I'm tempted to joke that he'll be claiming to have ended the Chaco War (1932-1935) next or prepare the Czech Republic and Slovakia for Trump claiming to have brought peace to their longstanding conflict.

Really though I think he might start just picking the names of countries out of a hat. Announcing he's the President who brought peace to the decades long war between Tuvalu and Kazakhstan!

Perhaps Gerald Ford can explain to him why Cambodia is considered the most heavily mined country on Earth.

He's already had Malaysia's role in rubber production explained to him. While the conditions the World Bank attached to bailing out the economic disaster that was Brazil's Fifth Republic are hardly a closely guarded secret.
