I read that statement as a signal of an Israeli about-face on the Ukraine war (they'd been very lukewarm, wanting to keep tensions out of Syria). Now that they're in the sorta same boat, Israel can't reasonably expect other nations to want to help Israel even as Israel had denied help to Ukraine. So I think this might be a result of US pressure to mouth the right words.
That is, I believe, the ulterior motive in play here. Everybody and their housecat knows Israel can't really hurt Russia without going nuclear.
