I know a lot of people on here hate the prequels....but i usually love all things star wars...except The Phantom Menace...I really enjoyed Attack of the Clones and I think Revenge of the Sith is up there with the OT. I feel you guys in regrds to being pissed off at Lucas for tampering with the OT and I too would like to see them restored an offered in high quality...almost like a Criterion Collection set that offers all the versions in HQ and let's the viewer decide which one to watch.
That was just a little about myself but now on to your question.
Sideous doesn't care about Nute Gunray he just wants to use the dilemna to become chancellor. He also wants Nute to have the knowledge that a Sith is orchestrating the politics in the Republic. This will cause Nute to align himself with Dooku in sincerity, which answers the other question as to why Dooku told Obi One the flat out truth.
The whole point of Episode 1 was to have Nute betrayed by a sith who is running the politics in the republic. Dooku says this in episode 2. The viceroy of the trade federation came to him for help after being betrayed by a sith who is orchestrating and influencing politics in the republic. Dooku flat out tells this to Obi in order TO LEGITIMIZE THE INCENTIVES OF THE SEPERATIST AND MAKE THEM APPEAR GENUINE. Blinded by their loyalty to the Republic the Jedi flat out ignore the truth even though it was told right to their face. It makes sense because Dooku and the separatist were villainized by wanting to separate from the republic and especially being caught red handed illegally creating battle droids. not to mention Dooku left the Jedi order...making him appear more like the sith that's causing all the trouble, not the one Nute Gunray was supposedly talking about. This is why Obi One refused to believe the truth because he caught Dooku red handed...why would he believe him? In Obi 's view Dooku is the Sith, he caught him red handed, so Dooku telling him the truth appears like deception.
I think this plot point was really well written and I think you guys don't give Lucas enough credit for this because you're blinded by your hate for him for obvious reason (tampering with the OT, jar jar)
Technically the sith were on both sided of the war!
The sith like to hide in plain site.
It's not that hard to make sense out of. I think too many of you guys are blinded by your hatred for the prequels that you simply close your minds to them. while I hate Episode 1 for lack of story...2 and 3 are great in my opinion.
read the star wars novel "DARTH PLAGEUIS" that's the real episode 1!! Hardcore, compelling, and made for an adult audience.
