Dreams of "peace" tend to be farfetched. If peace means warm relations and no tension ever, and if that's the goal of negotiations, then negotiations will never lead anywhere. Various Israeli governments talk about "difficult sacrifices" in return for "peace", but the implication is always that the only peace worthy of those sacrifices is a everlasting / kumbaya / we all love one another type of peace.
A more realistic goal is basically a perpetual truce. We can call it a "peace" agreement while being aware that it would be a tough agreement where most people will be unhappy, and where there will still be tension and even occasional violence. But if we're ever going to get out of the current endless cycle, we have to understand that even that kind of peace may be worth some "difficult sacrifices". And hopefully, that might even, over time, progress to a warmer peace.
