"And this fake dispute with Duke Leto," the Emperor purred, sinking back into
his throne. "How beautifully you maneuvered it."
Why did the Emperor think the Baron had a fake dispute with Duke Leto?
I always interpreted it as political CYA... he's making that public
statements to set up his extricating himself from any suggestion that
he assisted in the original invasion. Don't forget that (if my memory
serves) he makes that statement while receiving the Baron in front of
the Court, etc.
(In other words: "Sardaukar in Harkonnen livery? What Sardaukar?")
Are you saying that if people thought there was a fake dispute between the
Atreides and the Harkonnens, they would be less likely to believe that he
Emperor was mixed up in it? However, who would believe it was a fake dispute.
Hadn't the Harkonnens displaced the Atreides and caused Leto's death?
And there was the old feud:
"There'll be much bloodshed soon," she said. "The Harkonnens won't rest
until they're dead or my Duke destroyed. The Baron cannot forget that Leto is a
cousin of the royal blood--no matter what the distance--while the Harkonnen
titles came out of the CHOAM pocketbook. But the poison in him, deep in his
mind, is the knowledge that an Atreides had a Harkonnen banished for cowardice
after, the Battle of Corrin."
"The old feud," Yueh muttered.
This doesn't sound like a fake dispute.
Wasn't the Atreides/Harkonnen feud a pretext for the real dispute
between Leto and the Emperor, stemming from the Emperor feeling
threatened by Leto's popularity in the Landsraad?
