Anakin is the key to the whole thing true, but not in the negative sense you're saying.
First off, Anakin isn't the start of the problem. Arguably the Republic is, and arguably Jedi like Mace Windu are. I believe it was the RotS novel explaining that Mace Windu broke the Jedi code about no attachments. He loved the Republic, was a fanatic about it. It shows in that he was willing to do a coup for it, and even earlier do heavy surveillance on the Senate for it, all arguably outside the scope of the Jedi. Yoda also said it himself, the Jedi were too arrogant and sure of themselves.
You can also place the blame on who ever made the prophecy, or more importantly the entity that made the prophecy happen. The Force.
Without Anakin, the transition to the Galactic Empire isn't as clean, but it does happen. Anakin informs the Jedi who Sidious is that lead 4 of it's Masters to death quickly. Without Anakin that doesn't happen, but the 'plan' still goes forward. Order 66 may or may not take out Windu, hard to tell. Without Anakin there is no assault on the Temple by him, but the clone would still go. Do some Jedi get away? To do what? The Republic still falls and the Jedi are still crushed.
You know what doesn't happen without Anakin, the Emperor isn't killed. With no Anakin, there is no safety valve some 20 years later to make the 'correct decision' and off Palpatine. With no death of Palpatine, no Imperial fleet in disarray. No Rebel victory, no destruction of the Deathstars, the Empire remains.
Basically you get rid of Anakin, you ensure Palpatine's victory and make sure he stays for a long time.
Isnt part of the problem is that the Jedi didnt take the Sith's version of the prophecy into account? If they had, they would have known damn well what would have happened.
Assuming that Phantom Menace playes out basically normally...
Without Anakin, it is very likely that Count Dooku ends up killing or converting Obi-Wan Kenobi, a very dangerous prospect. Of course I'm presupposing that Obi and whoever his new apprentice is manages to get that far. It means that Padme and whoever stays on Naboo with her keeps there. Would Yoda and the Jedi come to rescue Obi-Wan? If not, the CIS can get the jump on the Republic. Not that it matters of course....
Hmm...Darkside Obi-Wan. Possible but unlikely. Although if he does fall, that means that if he turns back, Sidious could be fucked. I dont think Sidious could take on Yoda and Mace at the same time.
