Netanyahu's government unanimously votes to fire Attorney General who is prosecuting him for corruption

I'm in no way defending this situation, but what mechanisms would prevent this?

Forgive me, but as someone in the US I've had almost daily shower thoughts that, to my surprise, often end with me spouting the same thing that conservatives used to say (empty words, in hindsight).

How can we empower a government to check/modify itself to self correct when it becomes corrupt without the government having the ability to use those same powers to falsely check/modify itself to be more corrupt under the guise of removing corruption when the government itself is actually corrupt.

Basically, how can we create or maintain an organization that is empowered to do "good" when "good" can be made subjective? Or, how do we make what we consider "good" to be objective so that power can't be corrupted?

All I can come up with is a better informed population and democracy, but that's a tall order these days.

It's not a bug, it's a feature
