One important point: “ the other claims to use them as hostages while not really negociating their release either.” is false.
Hamas did and still agree to a biden resolution.
What happen after? Everyday israel kills a range goes from 15 to 150. Assassinate two of the main negotiator for hamas. Continue depriving civilian in gaza ( basically children and women) from basic life needed support ( limited food and medicine - limited access to water ) and ask them to move from corner to another safe place to bomb them again in the save place.
