This is far too strong a claim to make without support. You have no evidence of that and a huge unquestioned assumption that it’s impossible to have criticism of Israel decoupled from anti-Jewish sentiment, which would need at the very least to account for the many Jews whose opposition to what’s happened in Gaza is rooted in their faith. Given that Netanyahu has consistently had roughly ⅔ of Israelis disapproving of his decisions, I would especially need you to show your work explaining how your claim is compatible with the observable data.
