I haven't read much specifically about the politics history of WW2.
So, my question is...
Is there any evidence or suggestion that the threat was carried out?

Joe Kennedy died decades later.
Also, Churchill told the former king and ardent Nazi supporter that if he opened his pro-Hitler mouth one more time he’d be killed. They sent him off to be ambassador to a Caribbean island. To my knowledge the former king decided to keep his yap shut.
