A ceasefire comes about as an agreement between the parties. That’s why it is hard to get to (Hamas won’t stop defending Gaza, and the IOF doesn’t want to stop shelling/infiltrating). In order for the two parties to lay down arms even for a moment is with negotiations and agreements. We saw during the ceasefire, multiple negotiations, resulting in specific numbers of hostages from both sides released. These numbers weren’t decided at the time of release, they were specifics negotiated and agreed upon between parties.
Everyone that I know, that is calling for a ceasefire wants to see a permanent ceasefire. Not one that begins with Israel stating they will return to obliterating Gaza as soon as its over, but one that results in a process toward Palestinian self-determination, ALL hostages released both by Hamas and Israel. Keep in mind, Israel holds thousands of Palestinians hostage, including many without charge or trial and during the ceasefire, Israel detained more Palestinians than they released.
