The Clone army idea was actually brilliant, and it destroyed almost every Jedi with one clean stroke. And not only that, by being in the position of the Chancellor, the Sith could easily blame the Jedi for being the traitors, thus controlling both of the sides of the coin, which pretty much eliminated every opposition in the galaxy at the time. The Jedi were forced to use this army against the Separatist forces. Otherwise they were helpless against the sheer number of the droid army; As they said, the strongest ones, like Dooku, could've taken more of the droids and they could last longer, (such as Windu, Kenobi or Anakin) Dave Filoni: ''Dooku gets captured by a bunch of pirates... Yes. Now that I think is very hard to believe, except that there are 30 pirates around him. Now I agree wholeheartedly that Dooku is incredibly powerful. But the fact remains that if he gets into a fight with 30 pirates, yes he might kill 15 of them, but he will get shot and he will go down. All you gotta to do is watch Attack of the Clones. How does Count Dooku thwart those Jedi? Sheer numbers. Sheer numbers will defeat the Jedi.'' --- The Clone Wars Season One: Dooku Captured Featurette But in the end, the result would've been the same as they said. So the question is, if the droid army was the main plan of the Sith, which is overpowering them with the droid army only (and not giving the Clone army to the Jedi), what Jedi could do against the Sith? Could they oppose the Separatist forces somehow? I guess the survivors of the Jedi could get help from the Senate to have a small military power to some extent, after all the Rebels didn't even have the Jedi leadership, but they still manage to oppose the Empire's armies after 15 or 20 years, but how long the remaining Jedi could've fought, and how successful they could be?
