Wasn’t a big part of the Jedis’ problem their standoffishness?
Far from wielding power, they played at peacemaker and diplomat long after open war had erupted, resorted to questionably sourced mercenaries to do their dirty work, and relied enormously on prophecy to save them without properly understanding what it implied.
“Too Little, Too Late” might as well have been the motto of the late Jedi Order.
The power structure is the problem.
The lack of structure was a recurring problem for The Old Republic and the Jedi Order. The Trade Federation’s greed went unchecked early on, because the Jedi-as-space-cops presented no material threat. The Senate routinely dithered in the face of adversity, as it was easily subverted by staling tactics and backstabbing. No standing military meant a reliance on an assortment of killer robots, mercenaries, clones, and bureaucrats-turned-shock-troops, none of whom proved to be particularly reliable.
Far from “power corrupts” as the theme of the Prequels, I might argue the real moral was “power abhors a vacuum”. If you’re not willing to occupy the center of political gravity, someone else will.
