They could also have been making fun of a man that many people at the time thought was ridiculous.
Ed 8 visited Hitler with Wallis. They heiled.
Wallis was rumoured to be having an affair with a senior Nazi and passing him restricted info from the King's governmental papers.
Hitler planned to re-instal Ed 8 as monarch as soon as UK surrendered.
Ed 8 visited a labour camp
Ed 8 encouraged the bombing of civilians in the hope they would lose hope, surrender, and him and Wallis would be on the throne soonest.
The government were so concerned Ed 8 not fall into Nazi hands, as they thought may be imminent and not opposed by Ed, that he was removed from Portugal (I think?) and deposited in the Carribean for the duration of the war.
All of these matters were discussed and actioned at the highest level, have been declassified, and are now a matter of public record.
Ed 8 was a Nazi sympathiser, as was Wallis, and the other members of the royal family played along for far too long.
