None of that relates to this murder as based on the description of settler concerns, which are more of an issue in the West Bank rather than Gaza, I’m guessing that this happened in the West Bank. (Where Hamas is not the government.)
Whether the murderers are IDF or settler militants is immaterial to the point of this being an unjustified killing of a Palestinian shepherd living in the West Bank, who is rather unlikely to be a Hamas fighter or involved in the 7th October attack.
I prefer to use Main/Sub terminology. It also works without needing to change any acronyms.
