He's struggling hard for any meaningful support from Israel, beyond sanctioning Putin's many Jewish oligarchs (including the formerly richest man in Israel, Abramovich, who was practically expelled from Israel in March, after having been expelled from Britain back in 2018).

He's even a knight there, and he's an unusual one as he's been an American since the 1970s and only came to Russia after the Soviet Union fell (he was born in Soviet Ukraine). He's known as "the smartest one", Sir Blavatnik.
