From a Euronews article by Saul Anuzis:
"But in the last two years, things have changed. Azerbaijan won back the majority of Nagorno-Karabakh in a conflict in 2020. Today, only a rump remains under Armenian control."
The author's choice of "rump" in reference to an ethnical region with an ongoing deadly conflict that goes back centuries and has caused tremendous suffering to both sides doesn't seem right to me and sounds somewhat derogatory in a very subtle way. I'm not a native speaker but my knowledge of English is telling me something could be wrong with the term in this context. I'm not absolutely sure though. I've looked it up in online dictionaries and there is a use of the word in the sense of "what is left of a former organization, country", still wanted to check the specific context and how others perceive it. Someone cites an example of media referring to the unoccupied part of Czechoslovakia in the aftermath of Hitler's 1938 invasion as a "rump state". rump rebel organizations - "rump" used as an adjective
