True, but that didnt happen right away though. Yeah, by the time we get to ANH the discontent is more evident, which is why the Rebellion was able to flourish, but it's been a while since ROTS. I always imagined that the regular people barely paid mind to what was going on, just trying to survive. Yes, a segment was willing and ready to confront the emperor, but it was a minority at the start. That's how i see it anyways lol.
Thing is though it did happen right away. The thing is the republic was painted as helpless against the droids, so there's no reason they'd be any less helpless if the events of the movie didn't occur. The only explanation is Palpatine staged this whole convoluted plan for the soul purpose of recruiting Anakin, which is terrible storytelling in my opinion- especially since by the time we see him again in ANH he's just guy going in with the troops to rough people up.
Personally, i always saw the clones as Palpatine's play to destroy the Republic from the inside by manufacturing the war. He kept the jedi busy with the war (not to mention killing a few in the process, decimating their numbers) while slowly gathering more power to himself, using it as an excuse. The people's main focus was also the war, and he could get away with more stuff if people werent really paying close attention to what he was doing, like politicians do today lol. I think the ordering of the clones was him giving the Republic the tools for its demise, to weaken it. Of course he had to make sure he was in power in order to hand the Republic the gun that it would shoot itself with. A weakened Republic is much easier to take over than a strong unified one. I dunno, it works for me.
Okay but we saw absolutely none of this. We also saw that the fully unified Republic was going to be screwed if the droids attacked. Logically speaking Palpatine could've had Dooku do all that BS, held off on the Clones, had that Geonosis thing take place on Courescant instead with some type of horrible death toll- maybe even killing all the Senators. Declaring himself emergency powers to rebuild after the attack being some type of a war hero. Then he brings in the clones, rebuilds the place as an Empire. Hitler got his power after WWI by rebuilding Germany, Caesar got his power by being generous to his troops, I'm just saying if we're playing the speculation game that makes a lot more sense than "weakening the Republic from the inside".
Even following the events and logic of the film, Dooku was known to be a Jedi! The Jedi didn't even discover he was a Sith Lord until like Season 6 of TCW! All Palpatine had to do was be like "Hey! You know that jerk that killed a bunch of Jedi and tried to brutally execute one of you Senators over there on Geonosis? You know, that guy with the beard that's out invading planets and slaughtering the innocent? You do? Okay cool! He was one of those Jedi, so we're not cool with those dudes being around anymore." They could barely hold their own against the droids and the Clones mowed them down easily in Sith. Not to mention Sidious on his own took out like 3 of them and only debatably lost to Windu, not to mention was capable to fighting Yoda to a draw. The Jedi wouldn't have been much of an obstacle.
As for the chosen one, again no problem. Even Anakin was already fed up with the council by the beginning of Episode II, he thought it master was spiteful and overbearing, and by the end of the film they were keeping him from his lover and didn't teach him what he needed to save his mom. It's not like it would have been hard for Palpatine to be like, "Hey I'm rebuilding this place, you and Padme will be able to rule by my side happily, you'll be powerful enough to stop that bs with your mom, I'll let you stay out late on the weekends, oh and I know you already believe dictatorships are chill if the ends justifies the means so...you'll start monday..."
The whole grand plan was way over done in Episode II and it was acceptable in I and III, but still a bit much. Super complex isn't always super good, sometimes it's just super lazily written.
