Let's not pin it all on Netanyuhu, he is a good representation of his society.
At least according to this study, almost all Israelis are monsters who openly support genocide.
Not saying I agree with any of it, but I find the parallels illuminating. If anyone wonders why there's more anti-semitism now, s/he can perhaps compare it with how all Muslims are condemned as being members of a barbaric sect after any terrorist attack (yes, even attacks where the perpretator doesn't claim to be doing it for Allah).
Additionally the anti-Muslim hate was not "ah let's very justifiably cut ties with some mad country" it involved widespread and open islamophobia, calls for mass deaths and indeed invasions of muslim-majority countries.
The two situations are not remotely alike
