It's a matter of perspective the Klingon perspective is that the Federation invoked Head-in-the-Sand Management rather than confront the threat of Undine infiltration. FaceHeel Turn/ Heel≯ace Turn: The Klingon Empire withdrew from the Khitomer Accords for the second time about 20 years ago.And, on the other side of the card, all of the non-Klingon member races are definitely showing signs of being influenced by Klingon culture. The Nausicaans and the Letheans are mostly mercenaries absorbed into or hired by the KDF following the Klingon-Gorn War. The Gorn still have a measure of self-rule, the Ferasans are completely self-ruled but members of the Empire, and the Orions are allies by treaty. The Klingon Empire is still an empire but the Federation influences have affected the government. The Empire: For once, actually played with.
A definite case of Tropes Are Not Bad, as the Ferasans have had a chance to distance themselves a bit from their source material and become a unique race: In this continuity they're the progenitors of the Caitians, who broke from Ferasan culture over genetic engineering (the Ferasans were for it, the Caitians were against). Captain Ersatz: The Ferasans for the Kzinti due to copyright concerns (they're technically part of the Known Space- Verse and thus belong to Larry Niven's estate).The traditional government of the Klingon people has undergone some changes in the 30 years since the TNG era.
