Dooku was working with Sidious. Dooku knew about the clones, he couldn't say shit to the guys round the table coz the Trade Fed were there. They've already been fucked over by Sidious, so Dooku plays along with them, to get this army built. So it could attack the Rebpulic, so Palps could put forth a Clone Army, which Dooku has already ordered (it's so obvious it was him. Dooku left 10 years ago, the army was formed 10 years ago....) and this is all for Paps/Sid to control the Galaxy.
See!!
Man, I talk the talk but can't walk for shit!!
