Israel's real enemy won't stop and won't surrender until that country and it's people don't exist. They have taken the innocent civilian's of Gaza / Palistine / whatever you want to call the area hostage. They are also so ingrained into the region that resources are literally siphoned from humanitarian sites like hospitals into deep tunnels beneath; as just one example of reporting I'm inclined to believe is credible, even with the mutual atrocities both sites are carrying out.
What would winning look like from a moral and ethical standpoint? Liberating the people of that region from the violence and suffering. Return them to a functioning society with social and civic infrastructure. Fully deny major violence and terrorism in the region for LIFETIMES to the point that the hate and anger finally cool off enough for people to move on.

Winning is going to require a multi-generational investment in humanity by humanity. It's going to require the buy in of the people on the ground. It's going to require a United Nations coalition and boots on the ground from interests in that region who want to raise everyone above the hate. Also the afflicted country will need to be an absolute DMZ for that entire time. Membership in the UN peacekeeping organization the only military service allowed (and then likely in other countries).
Getting from here to there? Even less popular than the hugely unpopular war(s) anywhere else in the world. Don't ask me how anyone could do it, those skilled in the art of diplomacy have tried for longer than my lifetime and probably longer than your's and NOTHING has stuck.
