Here's the thing. I don't know how planned all of this is.
The current war(s) clearly serves just to extend Netanyahu's time in power as much as possible, because he knows that as soon as elections come, he's out of the premiership and into (hopefully) jail.
Now that tensions in Gaza have lessened, a war with Iran is the most obvious option. It's true that Netanyahu convinced Trump to abandon the previous nuclear deal, but this was before his criminal indictment (minor point: but after the investigations) and I don't know if he planned that far forward.
Meanwhile what considers itself the “left” in Israel is still very much genocidal and imperialist.
Until recently I would have agreed with you (other than the actual hard-left which consists of Hadash, Ta'al and Balad, two of them being explicitly Palestinian parties), but recently, and also a few times in the past, the leader of the Israeli Democrats (a new party with a terrible name) said some really based stuff which is a step in the right direction if nothing else. And now they're trying to take away his military credentials, which just shows that he's right. But even he can't abandon liberal Zionism, and a bit of militarism, if he wants anyone to listen to him.
It's more that the left is small and insignificant, because it has many of the same problems as the left in other right-wing countries: it advertises to a progressive middle class, and completely ignores the lower classes who would most benefit from its policies.
Left-wing policies in Israel will certainly help disadvantaged people, but left-wing (Zionist) parties talk about abstract ideals like "democracy", instead of material conditions. And citizens who struggle under the cost of living, almost or actually in poverty, don't care about the type of government they have: they care about surviving to the next day, and left-wing parties have just given up on trying to get their vote.
Essentially my point here is that Israeli society is not fundamentally incompatible with left-wing ideas or policies (leading eventually, hopefully, to anti-Zionism), but left-wing parties have consistently ignored those who need them most, leading them to the right and to distrust the left, effectively digging their own grave.
As a fun fact, some interpretations say that by binding Isaac and being ready to proceed, Abraham failed the test, either in the eyes of God or at the very least in the eyes of the author. The second verse has God saying (JPS Contemporary Torah)
Take your son, your favored one, Isaac, whom you love […] [emphasis mine]
And after stopping him, the angel (which is identified with God) says
I know that you fear God, since you have not withheld your son, your favored one, from Me.
The description of Abraham's love for Isaac is missing, despite identical phrasing (also in Hebrew) otherwise. It's as if God (or the author) is taunting Abraham.
This also raises a concern about God's omniscience; he says "now I know that you fear God", as if he wasn't previously sure. There are many ways to resolve this, but the Bible is just very inconsistent everywhere.
That's literally feminism
