Well, I mean, the reason they point out Israel's behaviour is because it's got similarities to what Russia's doing in Ukraine. Arguably, its even worse, given that they're essentially genociding people in Gaza who can't even fight back at all.
But if you're gonna shrug while Israel bombs Iran, because they felt like Iran was a threat so they wanted to pre-emptively strike them / their nuke program... then you have less moral footing to condemn Russia's actions in Ukraine.
And while most sane people think Israel should just... stop killing babies and stuff... the reality is that almost all western governments are continuing to trade / support Israel, even if they attempt to put on angry faces for PR reasons when talkin about it. Clearly Western Democratic nations have no issue trading with / partnering with Genocidal regimes who attack their neighbours, commit obvious Genocides, and threaten nuclear conflicts etc.
