Does the live-streamed genocide committed by the state on whose behalf the Labour Antisemitism Panic was initiated and weaponised reframe this period for you in any way? I mean, to some of us it was obvious all along that the treatment of Abbott was racist shitbaggery by a demented authoritarian faction hellbent on expunging any prospect of a moderate social-democratic government, but there's suddenly quite a lot of Noticing going on, even by people who were busy shitfunnelling hysterical bullshit at the time...
I suspect you are imputing far too much long-term cohesive strategy to what was short-term opportunism on the part of the right wing.
The biggest winners from the Labour's anti-semitism crisis was the Tory party circa 2019. It wasn't Israel, and even if Labour was currently issuing unmuted criticism of Israel's current war crimes it would not make one jot of difference to Israel's trajectory. The Tories used Corbyn's ineptitude to maximum effect. Naturally, the right-wing client press obliged.
The anti-semitism crisis of the UK Labour party may have been welcomed by the Israelis, but I do not believe it was "initiated on their behalf". It was far more cynical.
If you want some evidence have a look at the key Jewish voices within the Labour party, and what they were saying about Israel in relation to the conflict pre-2019.
Here is Luciana Berger, for example in 2018:

Have a look at what Margaret Hodge is saying now about Israeli actions in Gaza. It doesn't fit in with your conspiracy theory.
Abbot was suspended for suggesting Jews do not suffer racism. I find this weird given that I lived in Abbot's constituency when she was first elected, less than a mike from Stamford Hill, where Jewish primary schools were surrounded by barbed wire, such was the frequency of attacks.
For her to say this in the years following a crisis that nearly did for the Labour party is beyond idiotic.
