Based on my reading about "proportionality" in the current conflict, it seems the predominant call is for Israel to simply accept a cease-fire, which by definition means stopping all military action. But what these "experts" don't say is what Israel should do when Hamas starts firing rockets again, which is reportedly what ended the most recent agreement and hostage/prisoner exchange. Fire the same number of rockets back at Gaza, which would be useless and branded as indiscriminate as Hamas launching at Israel?
What most people who comment on the war don't acknowledge, Israelis, especially in the south, live in constant fear of rocket attack, even during periods between wars. Imagine what it would be like to have to maintain safe rooms and shelters, knowing you and your family might need to seek refuge on a moment's notice at any time of the day or night. I've never been in Israel during an air raid alert, but I'm sure it's terrifying.
Israelis and Palestinians deserve to live peacefully. The problem is Hamas, which wants Israel wiped off the map. That's why Israel has said their goal is to destroy Hamas, which I don't believe is possible without obliterating Gaza, if then.
Unless the Arab states declare Hamas illegitimate and support a negotiated two-state solution, the cycle will continue. But that's unlikely to happen when some of those same states explicitly support Hamas.
