>> This, but further more, there are 100s of comments about "the genocide" here, but almost none about what Israel should do.
They should do what all other countries do when they are attacked: defend themselves and not seek to take the attack as an opportunity to invade their neighbours.
You want an example? Look at the recent India and Pakistan crisis, and the Thailand and Cambodia crisis that is only now being resolved. In both cases there was fire exchanged, war was on the brink, then it was held back and reason and peace prevailed. The countries in question won't be best friends, they won't like each other, but they're not bombing the shit out of each other, levelling each other's cities to the ground and ethnically cleansing their populations.
The difference in Israel-Palestine of course is that Israel has the upper hand militarily and by many orders of magnitude so it doesn't have to make peace. It can afford to bomb the Palestinians for as long as it likes, it can afford to ethnically clanse them even at the risk of ethnic cleansing turning into genocide, it can afford to impose a medieval-style siege on Gaza where no food goes in and no Palestinians come out, it can afford to do anything it likes and nobody can stop it, certainly not Hamas with its risible military ... I can't even say "strength"; weakness is more appropriate. The redoubtable Islamist terrorists fight with their grandfathers' hand-me down AK-47's from "terror" tunnels (that have to be called that to sound even vaguely threatening).
The maddening thing is that exactly because Israel has such overwhelming military superiority -and not just against Hamas, but also against Lebanon, Syria, Iran sorta, everyone around it- they can absolutely make peace if they wanted. Its enemies would surely prefer that to having to fight Israel. Even Hamas' founders once resolved to make peace with Israel and what did Israel do? It assassinated them [1].
It is clear that Israel has convinced itself, as a nation, over multiple governments and generations, that its best interests are served by making constant, total war on its neighbours. Israel doesn't want peace.
But, to answer your question: that's exactly what it "should" do; make peace. That's the only way to not make war.

[1] Sheikh Yassin: https://en.wikipedia.org/wiki/Ahmed_Yassin
Yassin on several occasions proposed long-term ceasefire agreements, or truces, so called hudnas, in exchange for Israeli concessions. All such offers were rejected by Israel. Following his release from Israeli prison in 1997, he proposed a ten-year truce in exchange for total Israeli withdrawal from the West Bank, including East Jerusalem, and Gaza and a stop to Israeli attacks on civilians. In 1999, in an interview with an Egyptian newspaper, he again offered a truce:[41]
We have to be realistic. We are talking about a homeland that was stolen a long time ago in 1948 and again in 1967. My generation today is telling the Israelis, 'Let's solve this problem now, on the basis of the 1967 borders. Let's end this conflict by declaring a temporary ceasefire. Let's leave the bigger issue for future generations to decide.' The Palestinians will decide in the future about the nature of relations with Israel, but it must be a democratic decision.[41]
It was shortly after once such truce offer, in January 2004, that Yassin was assassinated.[42] His second in command was also assassinated for the same reason. Can't find the article now.
