That's a great idea.
He can start by reminding them that he said there is no such border. That would get the show on the road with uproarious laughter.
Then they can laugh even more about the fact Trump claims to be in touch with the Indians about the border dispute, when the Indians say they haven't spoken to him in weeks.
And the Chinese can make fun of the laughable trade deal Trump said he was making with them just before the virus exploded the world economy.
What a hoot.
