Do you mean weakens the Hamas position militarily? Or do you mean weakens the Israeli position militarily?
I understand WB is Fatah controlled who are more inclined towards a 2SS which is why Bibi supported Hamas (until it backfired on Oct 7).
I also read a Reddit comment about how taking land from settlers and returning it to Palestinians would make the border larger and Israel more vulnerable but I don’t understand how that is so.
