Remember, the claim wasn't that all Israelis believe or support this. The claim was that religious motivations for violence exist. And a stronger claim that I think I have sufficiently defended was, that many influential people have these motivations.
If the weaker claim is that some Israelis have religious motivations or feel like religion supports their position - sure. But big picture religion doesn't play as large as a role for Israelis as it might play for Iran or let's say Hamas or the Houthis. Even with those more religious actors I don't think religion is the only driver, e.g. with Iran this is probably partly just a way to control the population vs. a religious belief held by everyone in the regime (not sure about the ex-supreme leader)
