The Clone Wars have always been, in and of themselves, from their very inception, the revenge of the Sith.
They were irresistible bait. They took place in remote locations, on planets that belonged, primarily, to “somebody else.” They were fought by expendable proxies. And they were constructed as a win-win situation.
The Clone Wars were the perfect Jedi trap.
By fighting at all, the Jedi lost.
With the Jedi Order overextended, spread thin across the galaxy, each Jedi is alone, surrounded only by whatever clone troops he, she, or it commands. War itself pours darkness into the Force, deepening the cloud that limits Jedi perception. And the clones have no malice, no hatred, not the slightest ill intent that might give warning. They are only following orders.
