I will never understand why Israel doesn't like Russia.
They seem like they should have a very close relationship considering that of Israel's 9.5 million current population around 1.5 million have been migrants from the former Soviet Union.

But Russia doesn't send that Middle East Welfare Queen nearly $4 billion per year. So there is one glaring reason off the bat for Israel to dislike Russia.
Russia also has close economic ties with Iran and they also have military bases in Syria. It's Israel that is always agitating against and literally bombing these two Russian allies. So there is another reason.
A third reason is historical which would make a Russia-Israeli friendship awkward.
Russian nationalism today is centered around the Russian Orthodox Church where the last tsar and his family have been canonized as saints and are now revered as martyrs.
In some circles this has been regarded as controversial since
"Other critics noted that the Russian Orthodox Church Abroad appeared to be blaming Jewish revolutionaries for the deaths and equating the political assassination with a ritual murder."en.wikipedia.org/wiki/Canonization_of_the_Romanovs
There is also this little discussed fact of Soviet history:
In answer to your inquiry :
National and racial chauvinism is a vestige of the misanthropic customs characteristic of the period of cannibalism. Anti-semitism, as an extreme form of racial chauvinism, is the most dangerous vestige of cannibalism.
Anti-semitism is of advantage to the exploiters as a lightning conductor that deflects the blows aimed by the working people at capitalism. Anti-semitism is dangerous for the working people as being a false path that leads them off the right road and lands them in the jungle. Hence Communists, as consistent internationalists, cannot but be irreconcilable, sworn enemies of anti-semitism.
In the U.S.S.R. anti-semitism is punishable with the utmost severity of the law as a phenomenon deeply hostile to the Soviet system. Under U.S.S.R. law active anti-semites are liable to the death penalty.

Russia apparently still has the death penalty on its books but not for antisemitism and there has been a moratorium on executions anyway since 1996.

Following this complete loss of Jewish privilege in modern Russia you can see why there would now be very deep resentment amongst Israelis.
