The unmistakable figure of President Trump stands beside King Charles on a red-carpeted raised platform.
When the president looks out he can see the ceremonial symmetry of the military reception, the neat lines of guards in bearskins.
All around are the castle turrets, the perfect lawn, the horses and carriages. And the band strikes up the Stars and Stripes.
This is the spectacle being put on show for the president.
