Re: Best and worst examples of diplomacy in Star Trek
I think Sisko in "Emissary" was a great display of diplomacy, trying to find common ground with a very alien species, helping them to understand concepts totally foreign to them but the basis of our existence. After he was done he had secured safe passage through the Wormhole and opened up a whole new quadrant.
As for worst: any diplomatic situation where Archer was involved pretty much.
