Eric Frank Russell's "The Star Watchers" aka "Sentinels from Space" aka "Sentinels of Space" (novel, free): Humanity's guardian angels get involved in its petty troubles
I like to be surprised by a story's twists, but this one uses magic rather than logic for this.
Story summary.It's a complex story with a lot of threads, but the main plot involves David Raven, an alien disguised as human. He's one of the two guardian angels on earth of unnamed god-like energy beings, primarily to guard against possible interference in human development by Denebs, another advanced alien race.
But much of the story involves only humanity. Human colonies on Mars & Venus want freedom Earth is denying them; so they've started a sabotage campaign on earth. Earth cannot stop them from coming in, or it will have to recognize them as non-citizens!
David will unofficially help the government put out the rebellion.
- "All wars go on for too long".
- On governmental secrecy: "What constitutes legitimate news was decided by the type of mind that insists that matters of major public interest must not be divulged in the public interest."
- "the most effective technique is not to fight a thing but set its own parts fighting one another."
- "The public will swallow anything providing it appears to bear the seal of official approval & is sufficiently long sustained & plays upon their fears".
