That would be my guess. I don't know when Lucas first had the concept for Star Wars but I know that he was pitching the concept at the same time he was pushing American Graffiti in 1971 so 1969 is in the right time frame.That, or Gerta's meeting with George Lucas. (Since the first Star Wars movie drew upon another Kurosawa movie: The Hidden Fortress.)
J. Edger Hoover becoming crab food ITTL and being replaced as FBI Director by Elliot Ness means that there is a much earlier crackdown on Organized crime in the United States.
I think he is the best kind of sleeper agent now, probably never even thinks about being a German agent. Best to let sleeping dogs lay unless you REALLY need to wake them. Especially if Schultz didn't record him, in which case the BII or BND wouldn't even know about him.
He's probably the luckiest and most useful person in the story that no one really knows about.John Aleshire is someone you keep in the cold only to be used in a dire emergency.
He is not passing any information or doing anything for the Germans right now and only one or two people in the BND has his name and code name.
The last time it was posted that he was directed by German Intelligence to do something for them it was to go after a rogue agent that Germany which was also in the best interest of the Americans.
He may never be exposed as German agent unless something goes seriously wrong...
Unless, the future archivist is someone we already know...I am really looking forward to the chapters when Germany's ultra-top-secret-burn-before-reading sealed files begin to be released to the public. Although some of them probably have 'Never to be unsealed' written on them. Still, I can see at least one BND/BII archivist sneaking a peak...
Archivist (peering over their shoulder): 'I wonder what's in this one...'
(Opens file, reads a few paragraphs, swallows and shakily re-seals the file): 'Oh. My. God. If this gets out it could trigger WW3!'
Later that night, the archivist wakes drenched in sweat after a nightmare involving the end of the world and, for some reason, penguins.
Archivist: 'Thank God, just a nightmare.'
Shadow in the corner: 'Oh good, you're awake. Get dressed, you read something you REALLY shouldn't have, so your being transferred and dress warm, Antarctica can be on the chilly side at the best of times.'
