Agreed. To go along with Yoda’s failure line from Episode III, I remember this conversation from Episode II:
Yoda: “Blind we are, if creation of this clone army we could not see.”
Mace Windu: “I think it is time we inform the senate that our ability to use the Force has diminished.”
Yoda: “Only the Dark Lord of the Sith knows of our weakness. If informed the senate is, multiply our adversaries will.”
