Why an early win can hurt your protagonist
An early win on the thing that measures the war reads to your protagonist as proof their false belief about themselves was right.
An unjust arrangement survives for years because resisting first is individually irrational, not because the opposition is strong.
When something's been wrong for years, it's rarely about power. It's that whoever pushes back first pays alone.
"They're too strong" only explains one side. It also makes everyone else in your world look like they never thought of fighting back.
The reasons that really hold people back are social. Someone has to go first and take the punishment alone. In Mean Girls, that's how Regina George stays on top. Cady can go after her only because she's new and doesn't owe anybody anything.
In Knives Out, every family member who could stand up to Harlan is also living off his money. So they protect the very setup that humiliates them.
In Encanto, Abuela's rules came out of real grief. Arguing with her rules feels like arguing with her dead husband, so nobody does.
Most people who could break a bad setup are also getting something out of it. That's usually enough to keep them quiet.
So go through your world one person at a time. Write down what each of them gets from leaving things exactly as they are. That list is what really keeps the wrong in place.

An early win on the thing that measures the war reads to your protagonist as proof their false belief about themselves was right.
The opposition has to reward the specific false belief your protagonist carries and punish the truth that would free them, or it is generic pressure.
If you can move your two sides somewhere else entirely and get roughly the same story, your setting is scenery rather than the conflict in physical form.
