I don't think any other government in Israel would respond materially differently to Oct 7th. The only response Israel has to this scale of event is to re-occupy Gaza and the only way it can be accomplished without larger casualties on both sides is more or less what is transpiring today. I'm sure there are details that would be different but I don't think the script would be materially different if Likud was not in power. The military plan for re-taking Gaza is from the IDF, not the government. Likud-controlled IDF isn't really a thing, the government gives a target (removing Hamas) and the IDF executes. Any other government would give the same target.
What I would and do blame the current government for is that Oct 7th even happened, the scale, and the immediate response.
EDIT: I also blame the current government for trying to eliminate any possibility of a two state solution and effectively supporting the Hamas rule in Gaza as means of accomplishing that. I can probably blame them for lots more. That said the actual Oct 7th attack is all on Hamas and the response is pretty much the only response you'd have seen from any Israeli government (or anyone else in that position for that matter). We're in a place today that is a different place and we can talk all we want about what other possible places we could be.
I'll agree with you on the west bank policy being a Likud/right-wing policy in general. We can also talk about why the Israeli public is more right wing leaning and the left has all but disappeared.
I think those two groups are really more mutually exclusive than what you're trying to portray. At least to most Israelis they are. Because for most Israelis, when you say "peaceful within 1967 borders", it reads as "kill all the Jews in Israel". Many (most?) Palestinians will also not accept this statement because they consider Israel in the 1967 border to be the Palestinian state. If there was an overlap we wouldn't really be where we are, we'd have peace. I have not met many people who are in this overlap, i.e. they're both "pro-Israel" and "pro-Palestine" in a meaningful way. Most people do not hold nuanced views at all, don't know that much about the conflict, don't really understand what's going on, hold on to simplistic narratives and "windows" they get from the media and social media. For me as an (ex-) Israeli your equating the response of Israel to the Hamas puts you squarely in the anti-Israeli camp. You blank statement "massacre of civilians under the orders of Likud (and other far right parties)" feels like a blood libel. This is just my emotional response to how you phrase things. So that doesn't seem to be an overlap of pro-israeli and pro-palestinian.
