Retief and the Peter Principle
Inspired by James Nicoll's essay on SF and the Peter Principle.
For those not into 70s SF, Jaime Retief is the protagonist of Keith Laumer's more light-hearted ironic post-Golden Age space opera stuff, a counterpart to his grimmer Bolo stories (albeit potentially set in the same universe, or Retief is in an AU of Bolo). He works for the Corps Diplomatique Terrestrienne (CDT), a secret agent of the James Bond mold masquerading as yet another ineffectual CDT drone. The typical story involves the CDT trying to do something stupid on an alien world, and while technically following orders Retief manages to salvage the situation by just being So Much More Clever than his ostensible superiors. A common point of tension is that the Terrans have the military might to crush any opposition, but without Retief (and possibly a few others like him scattered about), the Groaci would eat our lunch and dominate known space.
It's basically read as a broadly satirical take on U.S. attempts at diplomacy, a comedy of errors against an enemy that shouldn't be that much of a challenge but somehow is (Groaci war tech is mostly knockoffs of older Terran tech, and they don't have nearly as much of it). So, Retief has to make sure he has the proper hemi-semi-demi-formal leisure suit for the afternoon meeting, while also keeping the Groaci from stealing a planet out from under the CDT. Retief's boss is good at covering his own ass, taking credit for Retief's actions (especially those that were ostensibly direct violations of orders), etc. Classic struggle of the only competent guy at the company to keep things from falling apart when the institutional culture is just crap, right?
Now...it's quite possible that this surface reading is all that Laumer intended. But, while it's been many years since I read the books, I never got the impression that Retief himself though "blow the Groaci away" was actually a preferred solution. Whoever Retief really answers to seems to be generally okay with the "diplomats, not armadas" policy.
Potential Death of the Author time. Regardless of what Laumer really meant, these days I see the situation as a case of the entire Terran government suffering from the Peter Principle, in which they have been promoted above the level of their competence.
They are very good at military solutions. It's often pointed out that they could throw a switch and roll over the Groaci-held worlds on a moment's notice, without scratching the paint on the dreadnaughts. But at some point in the relatively recent past, they decided to be Better. To work towards diplomatic solutions, make allies rather than vassals. And the ludicrously incompetent actions of the Corps Diplomatique Terrestrienne demonstrate that no one really knows how to do that. The warlike phase went on long enough that institutional memory of diplomacy was lost, and they're forced to fall back on historical records going back to when Terrans were restricted to Terra. They desperately want to be the United Federation of Planets instead of being the Empire, but it's outside their competency. Meanwhile, the Groaci (and probably some other minor powers) have realized that this levels the playing field a LOT. They can do stupid and bad diplomacy as well as the Terrans can, and it's a lot more likely to get them what they want than trying to pick an actual fight in which they'd get vaporized. Some of them might even be honestly better at diplomacy than the CDT.
Retief's job, then, is to troubleshoot the process. The true brains behind the Terran government are smart enough to know they have no idea what they're doing, a lot of wheels are being reinvented and turning out to be rectangular. So Retief is put in a position to chisel them into a more round-ish shape before disaster happens.
Retief is the sergeant who keeps the newly minted lieutenant that is the CDT out of trouble, while being careful to maintain the illusion of the chain of command. Hemi-semi-demi-usually.
