Absolutely Israel is fighting for its survival. 7th of October shows that Israel must destroy all of its enemies that surround it. Hamas and others were supplied by Iran, which must be stopped from developing a nuclear bomb specifically because it would be much easier to just get that bomb into Israel through Gaza and blow it up in the middle of any city, most likely Tel Aviv or Haifa (they wouldn't do it in Jerusalem). Any 'civilian' within Gaza is suspect, that's where Hamas is recruiting from in the first place. I applaud Israel for making progress against Iran and now it must finish what needs to be finished all around it, especially Gaza.
Iran has policy of destroying Israel, it's their religious policy and policy of the State, so they are obviously interested in keeping all of the various local conflicts going for as long as it takes to destroy Israel. Israel is under a strategic threat, it's not just Gaza and Hamas, this was made clear when Iran started supplying Houthis with missiles. Hezbollah, Hamas, Houthis under the guiding hand of Iran and with support from ruzzia. That's what Israel is fighting against. Just because you don't understand it doesn't change their equation and they must not and will not give up, they must destroy its enemies to survive.
The fact that the Western world has been brainwashed and is now so antisemitic and anti-Israel just shows how effective the propaganda pushed from Iran with the help of the ruzzian troll/bot farms became, that's a weapon that must be taken seriously. It was used to brainwash Americans into supporting putin and ganging up against Israel as well.
